I tested my tank last night and relized my Nitrites were off the chart. My tank is 2 months old, and I have about 15lbs. of LR and about 15lbs. of BR. I have a 55g tank with 1 porcupine puffer, 2 damsels, 1 goldstripe maroon clown, black sea urchine, anenome, and a upsidedpwn jellyfish. I read that high nitrites can be because of over feeding. Currently I am feeding my puffer 5 small krill a day, and a cube of frozen brine shrimp, and a couple flakes of flake food. Is this too much, and if it is what shoul I cut it down to?
