You can also install a GFCI receptacle on the outlet feeding the aquarium. They're no more difficult to install than a regular outlet although they do take about a 60% more space in the outlet box.

Most states are starting to adopt the 2008 NEC and just about all the GFCI's sold these days have to meet the new code. If you can find an "old style" GFCI outlet at your local electrical distributor, you could probably snag it cheap. There's nothing wrong with it - it meets the 2005 NEC requirements - it just doesn't meet the current electric code. I put several the rent house I'm living in and they've saved me from myself a couple times!

Marineland just replaced the heater which is nice. They said that recurrent drying of the heater can cause the seal to crack letting in water. 1 - 3 water changes a week probably accelerated the damage to the seals. They also said that it's not possible for a dangerous voltage to be introduced to the water, but I measured a full 120V in the aquarium which is very dangerous. Also did a resistance check from the heater to water, and it was very low (almost 0) in addition to the resistance of the water so disregard the non-dangerous voltage theory.

Also, went ahead and installed a GFI outlet for the aquarium, even though I don't own this house. My Milwaukee PH controller trips the GFI every time it turns on, which is a pain, but probably worth dealing with vs getting shocked again. Had to run an extension cord to another circuit for the PH controller.

If your pH controller is tripping the GFCI, you're having more than 5ma worth of current going to ground somewhere which isn't good. I would advise chasing that down and addressing the issue as quickly as you can to prevent someone getting zapped again!

I've measured the surge at ~15mA, which exceeds the 5mA GFI outlet by quite a lot. 5mA is the current residential GFI standard in the US. Milwaukee Instruments confirmed that a 15 - 20mA surge is not uncommon when the solenoid switches on. The only solution I've found for this would be to install a datacenter 100mA or commercial 30mA outlet.
