Any questions, just ask them here. We are fellow reefers and are here to help. Definatley ask here BEFORE you buy anything. We have made many mistakes and can help you from making the same ones. Alot of Local Fish Stores (LFS) just want your money so some give less than good advice.
Research the question by doing a search. Believe it or not that same question has been asked 1,000 times before. Go to the "search" button and type in your search subject.
Anyway, welcome to the boards.
