Yah I have to hook it into the GFCI, I put in. I've been shocked 2 times in my life once about 5 years ago, and the other about 12, but those were very minor nothing like this. Lesson learned for sure.I’ve had that happen to me also, but with saltwater.
GFCI can save your life.
I like the idea. I’ve got a couple 40 longs I’m considering doing a stream tank sometime also.
Keep posting the progress pics.
