Many of you guys have requested this topic. This is the last tutorial in the Green Aqua series and it’s about lighting. Welcome to the beautiful world of aquascaping! And let’s stop here for a moment! Why do I say it’s beautiful? You obviously know the answer, because the aquariums are beautiful. And why are the aquariums beautiful? Let me tell you why! Because of the lighting. So why do I say that lighting is the most important in making an aquarium beautiful? I spent like 20 years in the film industry. And believe me, there’s only one thing, that’s more important than lighting, and that is sound. But we don’t have sound in aquariums, so let’s just take the lighting now. ♪ Give me a light, show me what I need ♪ ♪ I know I’m blind, but I hear symphonies ♪ Light will make the viewer look at the object. And light always attracts attention. In order to achieve the beautiful underwater worlds, you need strong lighting. We are really lucky here at Green Aqua, because in the 10+ years that we’ve been running a Gallery, we tested tens, if not hundreds of different lights. ♪ ‘Cause there’s no going back, no going back ♪ ♪ There’s no going back to your old life ♪ ♪ Not living in the past, we’re over that ♪ ♪I’m feeling it tonight, we’re riding on the dizzying highs♪ So we, at Green Aqua, became subjective with time. And this video is putting an emphasis on the lights that we use. I don’t want to get into technical details. To tell you how strong is a light, when we measure it with a PAR meter. We’ve done a few comparisons of lights in the past. And we’ve also got numerous written articles about that, with photographs and everything, so if you wanna get into technical details, you will be able to do that. All you guys have to do after watching this video, is to choose the light that you like the most, take what we said into consideration and live happily with your aquarium, ever after. ♪ ‘Cause there’s no going back, no going back ♪ ♪ There’s no going back to your old life ♪ ♪ Not living in the past, we’re over that ♪ ♪ I’m feeling it tonight we’re riding on the dizzying highs♪ If you’re into DIY area, then you might be successfully doing your own lights. Here we’re gonna concentrate on brand lighting. So, let’s go! So you’re about to buy a new aquarium and you wanna decide on the lights. You’ve got to answer five questions. Do you have CO2 injection? That’s the most important. If you have CO2, you’re gonna be able to have bright lighting, you’re gonna be able to have that vibrant and lush growth in the tank. If you’re thinking about a low-tech tank however, you cannot buy strong lighting, because that will cause a lot of algae. The second question: How much money you wanna spend on it? Because even if you’re making a high-light tank, you can choose between different products, that come at a different price. Third decision you have to make is that do you want a T5 tube, a fluorescent tube, or an LED light. The fourth thing that you have to consider, is: Are you gonna sit on a couch right next to the light and does strong light bother you, or your spouse. Because if it does, then you shouldn’t choose LEDs, strong LED lights, because they can be really, really strong. The fifth question, you’re gonna to ask yourself, is: Do I want a standard aquarium, or not? If you have a non-standard aquarium however, your choice will be restricted, because you need to fix that light onto something. So what if you just started aquascaping and you want to have some plants in your tank, along the fish and you want to have some light above it, and you don’t know which one to choose. Our first recommendation to that is the Odyssea light. This is an Odyssea T5 tube. This is actually a compact tube. There’s no real difference between a compact tube and a T5 tube. So I think that these come at a very good price. These are entry level lamps. 6500K, this is ideal for the plants. It’s cheap, it comes with this thing, that can be pulled out. You can actually adjust it to your aquarium size. We do have some LED lights, that are cheap and… not cheap, but come at a good price. I don’t like to say cheap. And this is the Dennerle light. Nice light and it’s not very strong, so it’s suitable for non-CO2 environments. Alright, we’re back in business! High-light tanks, CO2 injection, we’re in the high-tech category now. And you’ve got quite a few options there. But be aware! When somebody says that the light is strong, that does not mean that it’s visibly strong. So actually the plants are utilizing something, that is measured with a PAR meter. So if I was on a budget, and I wanted to do a beautiful, but big aquarium, I would probably go for an ATI T5 light. It’s using the Sylvania tubes, the 6500K one, and you’ve also got the reddish tint, which will accentuate the color of the red fish, or the red stems, etc, etc. So what you can do, is just buy a light, that has four tubes in it. Use two tubes normal and two tubes red color. We like the ATI lights so much, that we actually have this above Dave Chow’s aquarium. We have two of them and we also got two of them above Ati’s aquarium in the background, and we’ve got some above the planted tanks here. If you have like a higher tank, then you will need a very much stronger light. That’s where you’ve got to buy some LED lights. And there’s also a very big difference between the LEDs and the fluorescent lights. The LED lights are coming from one source. So they’re coming from one point, which means that you’re gonna have a lot of shadows in the tank. And you will actually see the water surface movement on the gravel. And you will see a so called shimmering effect. The ONF Flat One. It’s a 90 centimeter ONF Flat One and this is the biggest ONF light to date and we’re waiting for a 120 size to be released yet. But this 90 centimeter light is really enough for 120P aquariums. As far as the 60 centimeter tanks go, we’ve got an ONF 60 centimeter light above the 60P tank. We’ve got the TwinStar light there and we’ve got the ADA Aquasky Moon, which has been discontinued. And we’ve got the Aquasky G, this light, the 60 centimeter version of it. And when you’re talking about nano aquariums, that have CO2 injection, I would recommend you to get a TwinStar light, or get an ONF. This is a very sexy small light, the ONF light. Csabi has found me the name of it, it’s ONF Flat Nano and I’ve been presenting you with this light in one of the most popular videos on the Green Aqua YouTube channel, check that out! So let’s talk a little bit about the design considerations. Our favorites in this are are the ADA Solar RGB, the ONF and the MaxLite. All of these are pendant lights, which means that you’ve got to hang them from the ceiling, or just put a shelf above the tank and hang it from there. You will most likely have problems with the lights, that have legs. Kids and animals can knock them over and they can fall into the tank. I did that in one of the videos. Should the light be dimmable? Not necessarily. We don’t dim any of the lights here at Green Aqua. What we do is we switch them on, leave them on for 7 hours and switch them off. Actually the maximum lighting period, that I would recommend is 8 hours. And I would not recommend having a siesta in the middle. If you have longer lighting periods, you’re gonna have probably plant issues after a couple of months. You can adjust the lighting period with a digital timer, or with an analog timer. The analog timers are also really nice. The only problem is that if you have a power outage, then they will stop, so you’ll need to readjust them later. We’ve seen some ADA charts, that plants appreciate the green peak in a spectrum. And when you have that, they can uptake that better. And for example blue light goes in deeper into the water, than red light. We don’t like the concept of manufacturers, who come up with different blue lights, red lights, etc. They’re for show. What we do is we use the 6500K lighting from start to finish. We don’t want to mix our own RGB lights. So actually the 6500K is something, that is very subjective as well. Because you will see that one light is really reddish, the other one is greenish, and both of them will be 6500K. So it’s really, really strange. And I would strongly not suggest you, to look at the numbers on the fact sheets. ONF is a little bit reddish, TwinStar is a little bit reddish, the Solar RGB is also reddish, but not as much. I would say that the Solar RGB, if you can afford it, would be the best solution for a bigger tank. How many Solar RGB would you need above a 90 centimeter tank, a 90P tank? I would just put one. And above a 150P we have two here, and the 180P has three Solar RGBs above it. Thank you! Thank you so much! I’ve got a good life here. Obviously the T5 tubes will have to be replaced every one or two years, depending on the manufacturer. The LED lights are guaranteed, to work for you for a long, long time. Nowadays, these LED lights take up a lot of power. So even a Solar RGB will take almost as much power, as a T5, an ATI T5 fixture. You can buys these Solar RGB shades separately, they’re not included in the light package. Many of you guys have asked us, how far the light is from the rim of the aquarium. So I asked Csabi, to help us measure that and… So can you tell me, how much you have there? [Csabi] Thirty! Thirty! ATI light is… [Csabi] Twenty-seven! Twenty-seven centimeters. And what about Dave Chow’s aquarium? [Csabi] Thirty! Thirty! Okay, so between twenty-seven and thirty for the ATI lights and between thirty and thirty-five centimeters for the Solar RGBs. The top one is the Solar RGB. My favorite light. And it’s quite a sexy light. Look at this! And it’s got the heat dissipating solution. The other one is the ATI light, which is a German manufacturer. It has a really nice body. Not like that! This is the 60 centimeter version. It has six… No, it has 4 tubes in it. Make sure that you buy the good quality T5 tubes in it, because this light comes without tubes. I observed that by the time that I get the tea, it means that we gotta go home. And we gotta wrap this whole thing up. I’ve been talking too much. This wraps up the last tutorial at Green Aqua. I hope that you guys liked, what you saw.

  1. Congrats on the 100K again Green Aqua team, it is well deserved. I'm about to do my own testing on a few of the name LEDs out there and looking forward to putting it out there for folks to see – keep up the awesome content, here's to hoping I get lucky and can come out to Green Aqua in the future!

  2. Excelent like always. I started in the end of the 90's and i prove all the options (tubes,pll,hqi,led etc) and i think you can get excelent even same results with all options, but obviously with modern more efficient options you need less units than before so is more simply . I still love pll and hqi but today finally i accept that LEDs as the most efficient option, they do not need reflectors, thats is an advantage. Saludos from chile, someday i will visit green aqua 🙂 Guillermo Barrientos

  3. What is the name of the red/orange plant in you video to you left love the colour great video lots of information just new to the hobby

  4. Congrats for the 100K, i know soon you will double this😉
    Its always a joy to watch your videos guys. As i can see your new scape is doing just fine, looks wonderful, happy for it. Wish you all the best cheers.👌👍❤️

  5. Szia szuper lett a video😀😀😀😀, szeretnèm kérdezni nekem 110cm hosszú aksim van milyen lámpát érdemes rátenni co2 a vizet. Köszönöm előre is.

  6. How do you like the Flexi Mini light? I got it for a 50cm with lots of plants but not sure if it's enough. Might get co2 later on.

  7. Great subject. One question, if the tank lighting is on during 8hours, and the day light in house/apartment is on 15 hours (summer), it going cause some problems like algae because
    it bring indirectly lighting the tank? It dangerous because, plant + light – nutriment /co2 = algae perhaps?
    How we can do, without having to close the window (when you can not), or to ajust for having a good lighting period etc…? I know it's a good question 😅😁

    In the last video, about co2, i would to know a little more about what kind of co2 diffuser we need used for big, little tank, inline, reactor, diffuser, etc… And why, 😊.

  8. what about a tutorial on RO/DI units seeing as all your tanks use this type of water. which are good which are bad what types of RO units do what compared to RO/DI units

  9. I am planning to buy a 60p tank, what lighting should i get ?Twinstar 600S or ADA aquasky G 601 ? I really like the twinstar because of the nice red. But what's the better choice?

  10. I used to have the photoperiod 8 hours but moved to a 11 hours period. What are the most common plant problems one can experience after some months with a longer photoperiod? (ps. : don't stop the videos for too much time 😁) oh, and I have the controller on my 900e that starts at 25% intensity for half an hour, 85% on the next half hour and then 100% for 9 hours. 70% intensity after that, 25% 15 minutes later and then, lights out.

  11. in our country we use LED because more cheap ,and we use lens so it more spread , i want to ask something in your opinion is that some of rotala example rotala HRA or redblood the leaf more red if get highlight ? by the way nice tutorial keep the good work

  12. You guys are the best!!! Class😎, humer😄😂, beauty🌿🍀🐌🦀🐠, and top notch info✍🤔! Thank you Green Aqua! My favorite channel!👏🤗

  13. I completely agree with you regarding light being the single most important aspect, most folk for get this, but as a photographer of 30 odd years, good light is always something that gets me going. Sadly my aquarium is one with a lid on it, and a light inside it, so my options are pretty limited unless i take off the lid, something I am reluctant to do as i do have a rather inquisitive cat in the house!
    Might get rid of the cat…
    Only kidding Mylo =)

  14. wow! i like your videos, store……… its amazing! i would like some like that in my city😧, that is more than impossible🤷🏻‍♂️. there is b
    not enough culture of acuascaping 😭. someday i visit you😎

  15. Thanks dear for completing aquascaping basics tutorial lights, co2, filter,ferts, algae, water parameters… Congratulations for 100k subs😍🤘🤘.. i love the way you explain all these stuffs without much technical parameters… now i can start scaping my 36×15×18 inches aquarium and hope it will look like bit of urs at some point…
    Waiting for those two empty aquariums to be scaped in ur gallery…
    Please do a blackwater aquascaping tutorial for bettas..🙌🙌🙏🙏

  16. Thanks for your tutorial, I have one twinstar 900, but i neet to buy another of 60cm. Fertilization can be your next tutorial in a deep way… Using ppm's maybe using branded fertiizer's (seachem or easy life) and explain in your aquarium what quantities to mantain it beautiful. Thanks

  17. Congrats on 100k
    Love this channel

    I recently got Nemo light Aqua fresh series 24w for my 13 gallon (Liquid Co2) with inbuilt timer control for 24hrs light simulating sunrise and sunset.

    Any thoughts on this brands?

  18. Hello there. I really want to visit green aqua one day. Unfortunately, I live quite far , Mauritius to be more precise but i promised to myself to be there one day. Also I want to make a tank similar to one of urs. They look so perfect.

  19. what distance do you recommend between the aquarium 120cm × 50 × 50 and the light onf flat one 60cm × 2 more then15cm

  20. Seriously bro. Your getting to greedy with the ads. I couldn’t finish the video. I had to stop after having 4 comercial in the 1st minute and a half. The info seemed great but couldn’t get into it due to the distraction of your ads.

  21. Hi this lighting tutorial is super

    Im planing to make my diy led lights for my new Aquarium size 3ft X 18 X 18 (lbh)

    I'm have placed an order of total 56 power led in the ratio of 4:2:1 (cool white: warm white: grow light) am I going right??

    I have also placed an order for heat sink size 180mm by 35 inch

    Planing to use lens of 45 degree for cool white n 90 degree for warm n gow. Do it really need?

    Please suggest me the distance I need to fix between tank

  22. Thank you so much for this Video! In my oportunity, you guys are the best aquascapers that are alive 🥰 (r.i.p Takashi Amano)! I am from Germany, but I hope I am able to visit your shop … In a few years 😓

  23. Sir;
    Plz give me a ONF light i m vry poor …. can't afford this one ..plzzz sir think about this..i wish i have a aquacaper bt i can't buy all this thinks buz of money..😢😢😢😢@green_aqua

  24. Knocked my TwinStar 600S off my ADA 60P in the water :-(. Luckily was off and still seems to work 🙂 . Any tips to stop it happening again? Feels quite likely to happen again.

    Are you going to do any more videos around picking plants and livestock? Would be good to see a good video on how to pick livestock for a tank and appriote levels.

    Love the videos by the way

  25. Nice tutorial. Please can you give me the names of the plants at
    1. 2:27
    2. 2:40
    3. 2:50
    4. 6:06
    5: 7:46
    6. 8:13
    7. 2:50 (red plant on the wood)

  26. Why? Why would the light bring on longer cause problems? Is it specific plants you have found have this issue? I'm a professional gardener who has a lot of aquatic plants from a place in Ohio, usa called Mentor Marsh. Quite a few gathered from the center of a large sunny pond. I'm actually afraid to cut the light time because most of my plants are not tropical. You get colder longer but….we both go completely dormant when it comes to most any local botanicals.
    I'm worried less light will make plants think its fall. Lol.

  27. 2.5ft 100litres planted aquarium, use Seachem Flourish and Flourish Excel. Got BBA infestation. Kindly recommend best light

  28. Great video but I was just wondering how long do you keep your lights on and is this continuously or for example 2 times 4 hours spread during the day?

  29. I did not understand the comparison that was said about blue light going deeper than red light.

    What does this affect in plants?

    And compared to white light (green peak) what do blue and red light do?

    Can you explain better, please ?!

  30. Okkk so Thats the secret behind your CINEMATIC videos …!!

    I've a question for you btw.. !

    I'm planning to turn my African cichlids tank into a planted one… But the problem is its alittle tall .. About 30 inch ..

    What led light m supposed to go for if i grow a carpet of Glosso and plants like Rotala Macrandra ..??! (Shouldnt be a cheap one though, I wanna invest and forget about the lighting)

  31. Hi sir, my name is Sai and i'm from Myanmar. I'm just beginner in aquarium tank and, still learning to know better. As part of my tank's lighting, i am turning the tank's light on from 10am to 6pm, for CO2 run from 9am-7pm. But, i'm facing a minor case "algae" in everywhere such as on the plants, DW, store. Pls suggest me that "How can i stop them?"
    And, "Does the room's ceiling light can affect to aquarium plant?" bcoz my room is a bit bark and lights are around 3meter distance with tank.
    Looking for u reply and, thanks!

  32. hey, recently bought buce from local seller ..its kind of rare buce . but it is infested with green spot algae, green fuzz algae, and tiny patches of BBA. As of now I have put them in empty 10-liter nano cube (like quarantine). I am afraid to keep them in the main tank, I fear that it may spread to other plants. I tried scrubbing buce leaves with q-tips ..but it didn't work .. all 3 algae stubborn .
    can you tell me how to fix it ??
    should I use h2o2 ??
    I want it to be clean and algae free before I place them in my display tank. pls tell me how ??

  33. Great video loved the inside on more in depth look at Plant Aquarium Lights ! Keep up the amazing work love the video and thank you for sharing !

  34. I've been having issues with my Anacharis and Echinodorus browning on the edges of the leaves and my Glossostigma just looks kind of brown too. Does too much lighting cause this? Everything started getting really green when I started using the ADA Green Brighty Iron supplement but now they all look sad. 🙁

  35. I have ordinary two T8 led lights at 9 watts each. Around 1800 lumens combined. No kelvin rating. Is this enough for high tech plants at 10 gallons? Ive been discouraged since I always got recommendations for expensive lights like wrgb and i dont have money for that.

  36. Great infos as usual ! Now you made me feel bad about buying my latest lamp. Hahahaha.. I wish I could visit your gallery one day, it would be a dream come true watching those beautiful tanks. You and your team did a great job. ^^

  37. "Cheap no they not cheap they come at a good price" if only people say this at start of my tank i maybe suffer less from super stupid low light

  38. Can you guys do a video about the best fishes and invertebrates that suit aquascaped aquariums? Maybe fishes that are best suited with rocky aquarium and fishes that suits better aquariums with lots of plants and moss
    👍🏼😊 keep up the good work

  39. Make a video where you tell your story, how you transitioned from 20 years in film industry to running a aquascaping business .

  40. Sziasztok
    Nekem egy olyan kérdésem lenne hogy van egy Diversa 25literes aksim azt üzemelem Low-tech "üzemmódban"! Ennek a gyári világítása, 5.7w-os a led lámpa! Ha az előírást nézem akkor is 12w kellene! Lehet az a baj!? Kevés a fényem!? Nem nagyon maradnak meg a növényeim! Kérdésem az lenne szerintetek kellene egy nagyobb teljesítményű világítás!? És ha igen akkor mit ajánlanátok!? Segítséget előre is köszönöm!
    Üdv Robi

  41. Hi Balazs. Thank you for the lighting tutorial. i have a question. You said that you don't like "concept of some manufactures use red light, blue light" . But why you still use lots of Twinstar led light in Green Aqua showroom ?
