I have 180 lbs of LR in the tank and 15 in the sump almost all of it came from a few different LFS and some came from a tank thak was being broken down ( the guy was moving so he broke down and sold his whole set up) I think it originated on the piece of rock with the big polyps on it . It has been over a week with minimum light MH only on 2hrs a day and atinics on for 6 hrs and I do not see that much of a reduction if any in the total algae some of it has turned brown and some has not changed at all what is my next step? I have been feeding the fish for the past few days. I have an RODI system coming in this week as well as some buffer and Magnesium also I have test kits for both those items so I am not dosing blind. Should I do some massive H2o changes as soon as I am up and running with the RODI system?
