I was dosing Reef code for a few days to slowly raise the calcium and alkalinity. However shortly after the water turned whiteish. It is a 90 gallon display with 28 gallon sump. Everything living in it seems to be doing fine still. I assume it was from Reef code B since that is a white liquid however it always disapated after a few seconds. I have done a 25% water change and that cleared it up slightly and am currently pulling water for another water change. This has been going on for about a week now
