Many people have experienced false readings when taking them less than 24 hours after doing a water change/adding dechlorinator.
My nitrates this morning as I said before were 80 ppm. I added 5 ml of API Tap Water Conditioner early this morning and now I just got a reading below 20 ppm. Any thoughts on this? The nitrate level came down so quickly!
