I'm Casey, started a planted 100g tank. Planted, discus, tetras, pleco. I was wondering everyone's opinion.
I use RO
water and add Discus Essentials to add appropriate minerals for fish. I started using plant fertilizer, Kent Pro-Plant. It raises my nitrate level. So in trying to keep my nitrates below 20 ppm
. It automatically adds near 20 ppm
to my tank, so it makes me think I need to continue to do water changes.
Question: Is this artificially screwing with my nitrate drop testing kit? Is it truly raising my nitrates? Should I stop using and let the fish create natural nitrates for plants?
Thanks for all possible help.
