Right here is one of the best sources for your information on how to set a reef tank up...we are here to help, we have experiences, and most importantly...we are not here to make a buck like the LFS is...
Research here and abroad from impartial sources as to what you need, want and so on...most things can be had online for a fraction of the cost of local purchases...items like the actual tank are usually purchased locally due to outrageous shipping through common carriers....
Filters, live stock, and all other equipment and supplies are for the most part, far better priced online.
