I have a Perfecto tank 265 and it has these black braces across the tank. They look as if they are there to hold a lighting fixture not for support of the sides of the tank. I would like to remove them Im getting shadows from them and me no likey. Should I replace them with clear acrylic piece or can I just remove them completely with no ill side affects. Thats a lot of wawa to hit the floor. thanks Bobb
