thanks all..
im finally getting into dosing the tank with magnesium, calcium, and alkalinity.. Got the calcium up to 445ppm for now (gonna take it up to around 475), the magnesium is up to 1250ppm, and the alkalinity is up to 9.3dKH.. gonna bring the magnesium up a little more to around 1300-1350.. should be seeing some extreme growth soon on the SPS!!
