Okay, I know that there is a thread out there that has info on some sort of ceiling foam that is good to put underneath rocks in a tank. I'm rebuilding my 75g and will be putting in some extensive rock caves. Since I'm taking everything apart, I may as well do this too right? So the rocks never touch the glass bottom and if my cichlids dig, the base rocks are touching the bottom and won't fall....
Any suggestions on this? Or experience? Where and what should I use?
