Hello all. I've had my 75 gallon tank running for about 7 months now. All my levels are great except for my nitrates, I can't get below 40-60. I do 15% water changes every week, I do not over feed and my tank is not overstocked. I have a 20 gallon sump running (with a skimmer and uv sterilizer) along with a fluval 305 canister filter. The sump has only been up about 2 weeks, I don't know if I'm being impatient or if I need to take other measures. Like a huge water change. Any advice will be appreciated, I really need some direction. Thanks in advance.
