Hi, we have a 120g tank with sump and we started SLOW dosing NOPOX. Our nitrates were all the way up to 60 about 2 months ago. We started with literally 2ml of nopox, went to 4, then 6 etc until we started to see a drop in nitrates then kept it at the amount, 32ml, until we got to the nitrates we wanted to be at. Now we hover between 2-4 nitrate and I’ve slowly backed off nopox to 21ml. I want to figure out our “maintenance dose” but I’m unsure how to know what that is. Any advice? I’m worried if I keep it at 21ml it will bottom us out.
