Is it ok to mix vinegar and ethanol in your CaCl2 two-part solution?
I am reading the thread and also others, I am dealing with stubbornly high NO3 (50 ppm) and PO4 (0.8 ppm). Question @Randy Holmes-Farley , will the vodka-vinegar mix reduce both NO3 and PO4?
Thank you for the answer.Organic carbon dosing is a decent way to reduce nitrate, but for various reasons, one should not expect a substantial phosphate decline at the value you have.
