Whats your preferred background?

That really IS a neat idea. My concern would be detritus building up in nooks and crannies and nitrate level rising.

I'll have to try that out on my ten gallon when I set that up. Nice one cz!

Rubble rock background

:happy8: I'm still interested. Don't like the wholw stone stuck in foam concept. Wonder about the silicone, probably as long as it healed long enough. The epoxy may be worth a try. I'm debating on trying it on a nano or a thirty I'm not using. I still think if it was rubble, maybe 1 1/2 or 2 inch max. The appearance will be different. I mean the whole back top to bottom side to side. MMMMM I'm going in... wish me luck !!!

I'm thinking of trying that with a 20-long project I'm starting up
