I've never used epoxy to glue my rocks. I just stack them very carefully and keep adjusting them to make sure that they are snug, and balanced well, and don't shift around. Sometimes it's easier to do than other times. I recently added some rock that I thought would look good in my 6g work tank. I didn't have time to bother scaping it, and just threw it in and arranged it well enough that all the corals got light. About 3 days later on a Friday, just before I was gonna leave I decided I'd rearrange everything so it didn't look like a big pile. I called my wife to tell her that I was gonna leave in about 20mins. Luckily we hadn't planned on doing much that night except renting movies. I called her back about an hour later, told her I was having problems, and that she should just go pick out some movies. I ended up having to drain the tank, remove all the rock and corals and critters, and start from scratch. It took me nearly 3hrs. :angry7:
It was frustating and infuriating. I just could NOT get the rocks back in the tank in any way that looked good and allowed all the corals to get plenty of light. I'm still not completely happy with it, but I'll need to wait until I have several hours to spare one evening if I want to mess with it.
So don't feel like you're the only one that has issues with aquascaping. ;-)
Oh...And Kick ass model Aromano.
