Nitrates always at 0ppm or close to it.
I have been dosing 5ml of Flourish nitrate every other day for the past 2 weeks, and nitrates have never been noticeable on my nitrate test kit. I have used two differnt mixture solutions, one set that is brand new (2 month old).
I dipped a pipette into the flourish nitrate solution, then dipped just the tiny bit that stayed on the pipette into the test bottle, shook it up, took out half the water, filled back up again, then tested and it tested at 160ppm nitrate.
So I just dosed 15ml of flourish nitrate about a half hour ago... (15ml would raise 40gallons by 6ppm, and I have a 29 gallon tank, and now my nitrates read ~5ppm.
How often do I need to dose nitrates in this beast.. And if I need to use this much flourish nitrate, wow that could get expensive.
