I have a 210g tank that I am wanting to start adding some corals and need to figure this out. I moved the tank just under a month ago and the nitrates have already hit 20. the tank has phosphates as well. when the tank was moved the water was completely changed(100% new water) except for the little that was in the sump and fuge. the stocklist includes a lion, puffer and zebra moray plus 3 small damsels. I feed once every 3 days and not much. I was also thinking of adding more fish but dont think that is smart till I figure this out as well. what should I look at to figure this out?
