Getting shock big time HELP PLs!!!!!!!!!!!!

[moe]

Over this weekend I lost most of my fish, because of a mishap. Needless to say when I was doing a water change I felt pulses. I ignored them and thought nothing.

I continue and put my hand on the ladder and got shock really bad.

At that point I decided to stop what I was doing. Next couple of days I try trouble shooting and try to change some stuff around and unplug certain things to see if it help.

Today I had the time to work on my tank again, and move some more thing around. And went working on my fuge. As I finish cleaning the skimmer I plug it in. I was putting it in place and got shock bad. I thought it was the skimmer. I unplug it and touch the running water and again SHOCK!!!!!!!!!

What is going ON??????

Can anyone help trouble shoot this????????????

does anyone would like to take a look and get shock???????

any help will be appreciated thanks.
