This is my first time to try a saltwater setup. It is a 16 gal bowfront with 26 lbs of live sand w/ aragonite. 4 pieces of "dead" LR and 2 peices of florida LR. a Marineland Penguin Bio-wheel 150 and an Oceanic Biocube protein skimmer. I doubt this protein skimmer will be worth its weight in air, but I am giving it a shot anyway. I was curious what test kit I should buy to run a FOWLR for now, but possibly go to a reef tank in the future. The only additive I am dosing now is Calcium Bicarbonate.
