My 125 gal mixed reef tank is about 2 years old and all parameters are in check. I did a major cleaning ( all pumps and power heads, sump and pre-filters for all pumps) changed carbon. I do this once a month right around the 5th.This month I did it on the 3rd.(go me) I have not done anything that I normally don't do and my ro/di unit is still running 0tds but my water is really cloudy.:twitch: Any idea why?
