I've got a 75gallon tank. It's been running for about 1 1/2 years. It has 120lbs of live rock that's showing coraline algae growth, a 3 inch sand/crushed coral bed. Currently housing 2 clowns, 1 foxface Rabbitfish, 1 sailfin tang with head and lateral line erosion, 1 bi color pseudochromis, 1 Fiji damsel, large colony of button polyps, mid size colony of yellow polyps, 1 small colony of Orange/green zoo's. It's filtration consists of 2 Emperor 400's with the regular filter pad and the media baskets filled with ceramic rings, 2 Rena xp2 canisters with regular sponges, bio balls and ceramic rings and some polishing pads. My salinity stays between 1.023 and 1.026. I'm having problems getting the nitrates to go down. Should I ditch all the extra bio media and let the live rock and live sand do its thing. Just keep the canisters running for mechanical filtration and water circulation? I have slacked on maintenance and that's my fault I admit it. Just wondering if I have a nitrate factory on my hands.
