I was having a problem with my Nitrates in my FOWLR. After a Partial WC
My Nitrates were 20 ppm I did another Partial change and still hovering
between 15 - 20 ppm. I began looking for anything that could help and
came across Amquel + it says it would reduce nitrates 12 ppm and after
3 days of use, I saw no results. I did some more research and found a
few other techniques that have no adverse affect on my fish.
SO I will give this a shot and see how it works.
