Hi. I can’t seem to understand why my Phosphates spike after a water change. My tank is finishing up a mini cycle that it entered due to me adding a lot of dry rock. Almost all the readings are normal now except Phosphates. They were reading above 1. Then went down to 0.9 then today they were at 0.59 before I did a water change. about 2 hours after the change phosphate was reading 0.9 again. I use Hanna hand held checker.
thank you for your help everyone.
