I've had high nitrates for 2 yrs now. They measure 25 on a salifert test kit. I'm probably feeding to much, but I've got this sailfin tang & shes such a hog the other fish don't get much. The only place in my tank that might need circulation would be behind the live rock. Does anybody else have a power head blowing behind their lr? My tank is a 120 long, with 5 power heads already. I change water every 2 weeks ( 21 gal ), every week when the traits go higher.Ideas?
