I have a typical aquarium setup with Discus and Plants. I'm using Discus Essential to add minerals to RO
water. I have also been using Kent Pro-Plant for fertilizer for plants. This automatically raises my nitrates with water change to near 20ppm. Is it truly raising my nitrates, or artificially raising them.
I'm using RO
water completely. Tested it before adding anything: zero nitrates. Tested after added Discus minerals: zero nitrates. Tested after adding Kent Pro-Plant: 20 ppm
Should anyone have any comments on this...
1: anyone experience increase nitrates using this product?
2: is it just messing with my drop nitrate test kit?
3: is this harmful for my fish?
