Hello my nitrate is 2 and phosphate is 0.2
I use biofuel 6 mil daily ... But phosphate is high my tank is full sps.. What do I do for solve this problem Help me plz
I may have read it too quickly. I don't think phosphate is in a bad place. You could raise nitrate, but are your corals looking bad? If not having any negative effect I wouldn't worry too much about it.
Pretty common in my experience for PO4 to be elevated relative to NO3. If you have a fuge you can increase light cycle to help bring down PO4 and if that doesn't work or isn't an option running GFO will get you in range.
