So today I found out this is only about half the rock
Wow... They don't short you do they?!?!?
I kind of like the open look I've got going but I know I've got to get more in there for filtration if I can. Worst case I'll have a bunch of rock for my new mantis tank. LOL
Thankfully I only used one small piece from my previous tanks more out of nostalgia than anything else.
