GreenCircleGirl Posted July 10, 2022 Share Posted July 10, 2022 I find testing nitrates really frustrating. For the API master kit, my nitrate reading is always red….which means it is 40 or more…..???? I can’t tell the difference between 40 and 100 with the master kit. With other test strips, I have the same problem. I can’t differentiate the pinks to tell what the reading actually is. I CAN actually differentiate the pinks on the Aquarium Coop strips which is so helpful. BUT….the Aquarium Coop strips read 25 ish but testing the same water with API master kit shows dark red which means over 40. I want to shoot for changing the water when the nitrates are 50 ish. I’m trying to feel comfortable about doing fewer water changes and allowing the nitrates to be a bit higher for the plants, but I’m frustrated because I don’t know what to trust. How can things be so incongruent? Link to comment Share on other sites More sharing options...
