Hello,
Tank 220gal,1 year old, having 2nd cyano outbrake more than month, I think it is because of imbalance between no3 and po4, while NO3 were 5ppm my PO4 0.12, then I decided to start dosing DYI NOPOX, two weeks Dosing 20ml a day, every other day doing tests, and my PO4 were not dropping, so I started to dose potassium nitrate about 2ppm per day after few days my PO4 were 0.08, a left it with no adjustments, after 4days done test. and them my NO3 were about 20ppm salifert test kit, and my po4 0.06, then stopped dosing NO3, and today I have done tests, and now my NO3 still about 20ppm and PO4 0.04ppm,so my Nitrates not falling down at all, My target is about 10ppm NO3 and pho4 0.05. DO I NEED to start dosing trisodium phosphate to drop Nitrate or just increase NOPOX? I also have refugium 12hours working, but grape caulerpa growing very slowly... Cyano still going strong, I vacum it, not helped. I want to found best ratio dosing NOPOX to control low phos and low nitrate, also if need i will be dosing nitrate to not bottom out them. Going to shut down refugium later.
