And now, a word from the other side...
I have the original tacky tank. No corals, no live rock, and everything in my tank (with the exception of the 4" of aragonite) is artificial. Resin branch coral, resin rock arch (I may replace it with a copy made from a piece of base rock and a masonry bit), Urethane anemone, urethane cup coral. If I find Mount Wannahockalugee in the pet store, I'm buying it!
I am probably the only person on this board not running Berlin method filtration. I'm getting a skimmer, and may even break down and get some base rock, but live rock has too many hitchhickers for my (wife's) taste.
Fish Only Forever!
