Sand the floor in 12×9 size. Place the edge of the sand once again with a quartz block. On top of 2 blocks of sand, make a floor of 10×7 with spruce planks. Make a 3-block quartz staircase on the right. 3 blocks of glass blocks are stacked on top of the quartz blocks. Fill the water between the sand and the planks! You need to make the entrance and the inner wall with glass blocks. Make the room three blocks high and cover the ceiling with glass blocks. There is a space between the inner and outer walls. The ceiling part also has one space. Flow water so that the water below is connected with the water above. Cover the roof with a quartz slab. Wrap the bottom edge with quartz slab once. It will be easy to manage if there is a passageway to the aquarium! The aquarium offers a variety of tropical fish, seaweed, corals, kelp and more.
