Hey people.... I have a decoration in my tank, it looks like a rock formation and is made out of plastic or resin or something similar. It's hollow and in order to get it to sit on the bottom, not float up, I have to invert it let it fill with water and then put it in place. I got to wondering about that cup or two of water now trapped inside. Will that cause a problem in the tank? It's not filtered or moving in any way, so I'm thinking that the water quality inside would have to deteriorate over time. What think ye?
