Welcome to the dark side Mj
I will say this...plan everything out before you buy anything (except that book, its a must have item).
A Salt tank can be great fun, but can also be expensive. If you wanted a reef tank with corals and live rock, you could easily spend $2,000-$3,000 (retail) setting up a 150gallon. Reef lighting, and 200-300lbs of live rock are two of the biggest expenses...but also provide major benefits to the mini-ocean you are creating. Certain DIY
solutions can help you save cash, and careful equipment selection will prevent wasting funds on bad equipment.
I don't want to sound pessimistic or dissuade you from this...but I do want you to know what your rough budget should be. You can always start with FO
, and upgrade the lighting later on if you desire a reef.
