Hey Man!!! Glad you're ok. By you sharing this, it has me really thinking about the safety of my family and myself. I have four tanks and the last thing I want is to encounter a situation such as yourself. I've always thought about safety to a certain degree but not to the point that I should be thinking about it. It should be our number 1 priority in this hobby. I don't have a GFCI, so in the meantime, I will now always unplug a heater before my hands go in a tank. Glad you're alive to tell all about it. You're probably going to.end up saving someone's life. Thanks.
