I’m getting mixed results. I’m currently fighting bypropsis (sorry if I spelled that wrong.) I have been testing 0 for nitrate and phosphate on my Api test kit for about a month. Now that I have started this battle I decided to test using my Red Sea and my results are completely different. Still 0 and 0 on my master test kit, but Red Sea gives me these results. Which should I go off of? I am thinking about buying Hannah checkers for nitrate and phosphate, would that be a good idea? Nitrate on my api is zero, Red Sea shows this which definitely is not zero. I don’t have a Red Sea phosphate test, but my Alk for both are different, api giving me 7 and Red Sea giving me 8.5. My ph is missing from my Red Sea but api says 8.3, I am confused lol.
