My favorite tank is my 72 gal bowfront. It's been a well cycled thickly planted community tank and crystal clear for over a year. I put some new LFS fish in it too soon and Ich showed up after a couple days. To fight the Ich, I gradually raised the temp to 86. The water got cloudy. Does anyone know a reason for this or whether it is typical or not when the temp is raised to 86?
