    Some poorly grounded stuff...your water is "live". Powerhead? Filter? Light?

    Take out your internal filter and see if there is still this problem... The internal filter might have a crack and water is seeping into the motor and causing current leakage into the water...

    Turn off one of the appliance and see which one is causing the leakage. Touch a test-pen over the water surface.

    I always suspect the light set first. Touch the screw portions with a test-pen and they usually light up!

    try to use a test pen to check for electricity on all the electrical devices in you tank. if you cannot isolate which one is leaking electricity, use the method suggested by Koah Fong and switch off/on each electrical device individually.

    if it is the internal filter, replace it.
    if it is the light set, connect a wire from the casing or ballast to ground.

    Hi,
    As mentioned by Tawauboy, use a test pen to test for voltages. If confirmed, I would suggest unplugging one by one rather than switching it off. It sounds like the short is due the improper earthing, the current might still be loitering unless the main is switch off.
    Cheers and Regards,

    Check your heater - if you have one. I have the same feeling when my heater crack.... Install some earth fault protection devices, especially if you live with young adults.

    As a safety measure, you may want to place a rubber mat beside your tank. Always stand on it when you are working on your tank. The "current/short circuit"-like feeling is a result of earth-leakage. Some equipment is not properly grounded, so check your earth wires.

    when this ordeal is over, you may want to consider changing (where possible) your 2-pin plugs to 3-pin ones with the correct rating fuse for added protection. Get someone to help if unsure about electrical stuff
