nitrate test kits (seachem and red sea)
Just finished testing for nitrate in my tanks with both test kits
Seachem (color chart) reads 20 ppm+ their reference solution shows 10 ppm. Red Sea shows 0 ppm. What gives? Anybody else able to compare these 2 kits. At this point I'm more inclined to believe the Seachem results since I'm dosing KNO3 at 3 ppm when I should actually be doing water changes only and get my level down to 10 ppm or so. |
