Nitrate and Water Changes

[Milo]

I'm dripping about 24 gpd in my 265 with large fish. The nitrates went down with NO (manual) water changes and now they stay constant at about 15-20ppm. It was at 60ppm when I installed the system. I dont need an equation to tell me that it works or doesnt work. When I test the water and everything comes out ok, I get the answer.

20 PPm's is still kind of high, granted better the 60.

1 half of the acceptable amount of Nitrates is "still" high?...HUH!?!
My TAP H20 tests out at 10ppm nitrate

Yeah, I'm in the same boat. My water out of the faucet is 20ppm. Even if I did 100% water changes, it's never going to be lower than 20 ppm. With several tanks over 150gals., RO is just not practical. So I am now using drip. It keeps it stable, fish are growing, no worries.

hell you might even be able to clean up your Tap waters' nitrates with the dripper...
