Noticing slow growth and a few die offs and noticed I had small amounts of voltage in the tank. It was 1.2 to .08 without ground probe in and with the ground probe attached to my boiler i was getting a reverse effect of 40.0 mv. I since moved the ground probe to a better ground to which it reads 0. Now with a .08 to 1.2 can that kill off corals. The tips were dying off
