Hi Guys, Last night I read up on the threads in the beginner discussions about electricity and grounding your tank. I put my hand in the water to move a turbo and got a slight jolt. What really intrigued me was that when I tried to clean my glass with the magnetic algae cleaner, I got reverse polarity!!!! Meaning that when I moved from the front of the glass to the sides and separated the two parts, when putting them together again they actually opposed each other! That means that they switched poles by the electrostatic current in the water. Anybody ever had the same problem or any advice?
