May I ask where did you get the rocks you have on the back side of your tank?

Glad I could help

Hey, I just wanted to say I was looking at a post about ATO systems and you put what you have in there. I never thought of that and it seems like a really really good idea. Since I'm looking for an auto top off I will def try this out! And it's really cheap too!!!- Thanks alot!
