I have a 36 gallon, all water parameters are good except nitrates - about 40 ppm.
I am doing a 20% water change every two weeks, along with cleaning the canister filter.
I am using tap water, but I have tested it after I mixed it with salt, it did not have any nitrates at all.
is there any chemicals I can add to reduce nitrates?
i am using an API liquid test kit, is there any other better test kits out there?
help if you can
thanks
