So my par is all fine except for nitrates it is very high. A big whopping 160ppm. My question from the wise is what is the easiest way to drop them without doing big water changes. I dont want to stress anything out due to its probably what they are used to now. I have a 55 gal. With two clowns a niger trigger and lawnmower. I only feed once every other day 1 block of mysis frozen. I would say rough estimate about 120lbs. In live rock. Im trying to solve algae problem before it goes crazy, lighting is down to 2 hrs. Now.
