I need some help with this. This is for my turtle tank and my 40Breeder is almost full of water. I had to order some light stands for my lights...well I received them and had no idea they have to go under the tank.... http://www.amazon.com/Zoo-Med-Reptile-L ... +Full+Size anyways I have to drain the water to do this, I have a piece of Styrofoam under the tank, should I put it on top of the Styrofoam or under it? and I have to do it on each side, 1 on each..is this gonna throw my level off a lot and cause it to leak? I'm a little worried. Maybe these light stands are made for aquariums that do not hold water? Thanks!
