Nitrates
I don't know if I'm posting in the right forum or not, I guess someone will let me know. I have a 130 gallon softie reef. It's been up and running for almost a year. All fish and corals are doing great, but I can't get my nitrates under 20. I have upgraded my skimmer, I have added more powerheads ( I now have about 3400 gph flow). But no matter what I do they just won't go down. I have even started using Denitrate in a small reaction chamber. I only have 2 medium size fish and 2 small fish, so my bioload is not the problem. Any suggestions would be appreciated.
