Are you dosing per instructions on the bottle or something you have come up with on your own? I have always been afraid to add it but I have some. My Phosphate is exactly what yours reads now .03 and nitrates run between 18-23 usually. Would like to raise my phosphates without raising the nitratesI already feed a lot, plus that would also increase nitrates and overall detritus. Dosing pure po4 has been the best way to maintain it ime
