Epoxy is cheating to me. I was like that with reef and Im like that with fresh. I was obsessed with legos as a child and thats how I build the tanks- au natural!
But thats just me being snotty- epoxy works GREAT!!!! And ill use it on others tanks if need be.
The tank is actually locked together far more than it looks- only the top tiers are in jeopardy. And once the anubias grows in, I doubt more than a couple rocks could even move!
