My water was crystal clear last night. Not so this morning. I ran my heater overnight, which i rarely use, and now my water is a little cloudy and has a green tint to it. FC=8.5, CC=0, TA=140, PH=7.4, CYA = 30.

I use well water but always use metal control to keep them in suspension. Can running a heater cause metals to drop out of suspension
