So in having trouble keeping my nitrate stable, it always seems to high or to low or where I want it for a week. Phosphate is easy to keep stable where I want it using fauna marin .04 gfo. I have a refugium which is good at bringing my nitrate down but then it gets too low to and I put a tiny bit of nyos nitrate + and then the next week it's too high for my liking compared to my Phosphate. So how do you keep yours stable? Mine seems constantly up and down or like I say at a good number for like a week and then either way.
