However, when I turn on a light on my desk next to the tank that is plugged into the outlet on the opposite wall, my ph controller gets affected by a change in ph. The disturbance shifts the ph controller up by about .08 each time. The light must create some form of electrical disturbance in that circuit that affects the ph controller. I know the ph controllers are sensitive but I was wondering if there was anything I could do to isolate the ph controller, short of installing a new circuit. Thanks for any help that you may have from your own experiences with this phenomenon.

A well designed surge protector (not a $3 unit from Walmart) will
protect from just this kind of thing. You may need to get a line
conditioner if the surge protector won't do it. These can be bought at
CompUSA or BestBuy. To the best of my recollection, they run about $50.
