Nope the 600 gallon tank above is just more stingray space. Filtration will be through the wall and in the next room. I have two big bead filters at the moment for the start. And ya I won't be able to see from above which is plenty fine by me. I'll have the window to look through and be able to see under the tank. I don't have tons of space like many and this pond is already taking up a whole room but I wanted even more space for the rays so this was my best idea to get the most space possible in the same amount of space.
