I took @Lasse advice and started to test my system for NO2 and what do you think I found? I measured 0.05-0.1 ppm NO3 (the level varies). I am using the Hanna Total Chlorine Checker to measure the color intensity and Red Sea.. It is really there.
Lasse what does it mean??? Snails, sea star, fish and mushrooms don’t notice
