I have a Red Sea reefer 170 coming up on 2 years old an I have been having trouble keeping nitrate an phosphate down. I have accumulated 7 fish in the tank an a few coral mostly LPS. I feed frozen food everyday an have scaled back on the amount trying to reduce nitrate an phosphate but still rising. I feed coral once a week or once every 2 weeks an 20% water changes once a week. Would a algae scrubber or chaeto reactor help me or should I try other methods first?
