heres some tips, keep using RO, don't overfeed,set up a refugium if you can,add more flow if its not at least 10x tank size,open up rock work[some people tend to have a wall of rock which leads to dead spots] and drip KALK, slowly it will burn itself out. make sure your bioload [to many fish] does not exceed you filtration. Just ask DOO-EE about the loss of fish life and algea blooms when good advice is not taken.
