It's not leaking is it?

i agree with ed. if your divider was leaking, the water levels on each side of the divider would be equal. you tested it before adding the gravel right? if it didn't leak then, then it shouldn't be leaking now.

the fog inside the tank is just the humidity given off by the wet gravel.

Thanks for the quick replies, and yes i did. i put water in there and let it sit for an hour or so before adding the gravel
