I have a Mag 9.5 that I use for mixing water and it recently started tripping the gfci plugs in my garage. I tried all plugs in the garage and even 1 in a bathroom in the house. Same result. So like a true reefer I took a bucket of water, put the pump in it, plugged it into a non gfci plug, and stuck my hand in the bucket. It didn't shock me and works fine. Why would this pump do this and is there any way to fix it. The pump is about 1 year old.
