I think people rely a bit too heavily on nitrate and phosphate test results. I think we have a tendency to try to measure and control as many variables as possible, and in this blinding determination we fail to really look at the tank.

You say you filled up the reactor - exactly how much RowaPhos did you use? RowaPhos is quite aggressive. In my experience, too much GFO is much more detrimental than too little (or none). I hope you are adding your equipment back cautiously and "gently".
