I've been asking questions for a day or two now and have received so much great information - thanks to everybody!!
I bought a house in December that came with a 220 gallon tank already set up. It had 10 fish and live rock. No crabs or snails. I had a local store send a "fish person" out to show me how to take care of it and they told me it needed upgrading if I wanted a colorful tank.
We went on a 5 day trip and the electricity went out - yep you guessed it - no more fish and a stinky tank. I decided to have the fish people do the upgrades - the previous owners of the house were definitely DIYers and probably should have left a lot of the stuff they did to the professionals!!

(Tile floors are uneven and I keep stubbing my toes etc...) The pumps and skimmers were replacd and the plumbing more efficient. They cleaned off the rock and brought in some snails and crabs. Then they let me know that the lights weren't enough and I would more $. I wasn't ready for that yet - but they said I could get some fish etc.. in there with what I had.. I noticed all the crab and snails were dying and asked if that was normal - they said yes.. and then POOF the fish people vanished. After a few weeks of trying to keep the tank full of water with bottled water etc.. I decided it wasn't worth the stress and shut off the pumps and lights.
Then a few days ago I decided I was ready for the challenge of learning how to do it myself!! I thought it woule be a lot more difficult - but after finding this site I think it will be less stressfull and a lot of fun!!!
I'm in Rancho Cucamonga CA - if you're near me let me know if there are any LFS worth checking out!!
