I've been having difficulty to the past 6 months on reducing nitrates and phosphates in my 210 saltwater tank. I've tried about everything: weekly 30 gal
water changes, reduced feeding, GFO
/carbon reactor, clean out sump, NoPox. RO
water is at 0. Fish are fine, but corals are having a tough time. Any advice would be appreciated.
