You will probably want to describe what dosing setup you are using. Also, what are you trying to dose (Calc, Alk, Mag)? Are you using commerical products or Randy's 2-part? Lastly, setup of the proper dosing amount usually takes some trial and error and a lot of testing over the period of a couple of weeks or a month to determine what your corals are consuming and what amount is needed to replenish the consumption...
