Has anyone else had issues with low nutrients after installing a roller filter? I feed my 60 gallon aquarium pretty heavily which is stocked with a yellow tang, 2 clownfish, 2 anthias, 1 damselfish, 1 Cardinal, 1 mandarin, 1 firefish and 1 neongoby. I’ve always had a presence of nitrates, but since installing my ReefMat, I have to dose nitrates to keep levels up. I go through about 5ppm of nitrate per week.
