Firstly, I have 60 cube sps tank with a 29 gallon dump. Psk75 skimmer, jabeo DC return pump, jabeo dosing pump, Jabeo wp40, korallia 3 ph.
For the past month and some my nitrates have spiked heavily (50-100 salifert test). I do weekly 10 gallon water changes regularly. I've been doing more since the spike. Recently I've done 50 gallons of water changes this week and they still are testing high nitrate. 2 weeks ago I started using Red Sea no3po4x as a source of carbon dosing. My skimmer cup is filling daily.
I have not had any fish or invert deaths. No overwhelming algae, just some red slime. I removed the sump and thoroughly cleaned it to remove any detritus that might have been missed. It's clean as a whistle now. I only have 4 fish, an anthias, a juvenile sailfin, 6 line wrasse, clown. 2 shrimp and a few snails. I only feed them a few pellets once a day. I have a thin sand bed, maybe an inch. I have plenty of live rock. The tank has been running for 7 months but the rock and live stock I've had for a few years.
Can someone please give me a clue of where this nitrate it coming from.
