Welcome to AA licreek!! Although I am relatively new to this forum, I've already gathered some invaluable information from the other generous hobbyists. You should also think about buying a good book to supplement the info you read on these forums. The Conscientious Marine Aquarist by Fenner is great book that many recommend.
I agree with Theatrus that you probably don't need the UV
. A sump with a good protein skimmer will be a better route to go. You should definately think about getting some live rock. About 1.5-2lbs per gallon, more if you can afford it. The LR
should take care of a big portion of the bioload.
As for substrate, aragonite sand is highly recommended, although many others use CC
. A 3" sand bed should be sufficient.
As for your water, distilled is an option although R/O water is probably a better route. Like theatrus recommended, you can pick up a good R/O DI
filter from ebay for about $89 on ebay. I got mine from filterdirect. You'll save in the long run and make things easier for you when you do your water changes and topoffs.
! Good luck with your tank and remember to be patient!! You'll probably hear that over and over again, but it's probably the best advice I've gotten. SW
tanks take time for good things to happen. Do your research before you buy anything.
