Seapony's trials and errors... mostly errors.

I agree. Run some bio-pellets in a reactor and that will allow you to reduce the amount of rock work you need in your tank. I would highly suggest not piling rock up against any of the glass. This way you can get flow across your entire sandbed to avoid any dietritus build up. Also, you can clean your glass a lot easier.

Get creative. Drilling rock does work, zip ties, epoxy, etc. Just try your best to aquascape to your liking. Larger pieces allow you to make bridges, etc. and make the rock work look more interesting.
