Electrical current in water

[pondfisher]

mt set-up actually does not have any pumps submerged in the water using cannister filters and hang-on skimmer. I have just put a cooling fan on the back glass panel to cool the water tem which I must say works really welll. But when I immerse my hands in the water get a electricity shock. Thin dis due to the addition of fan cos b4 dat no shocks experienced?

can someone tell me how come there is a current in the water and izit bcos there is no grounding or earth wire (is the term correct?) for the fan? How can I overcome this problem would appreciate some advice.

stray current can leap boundaries. from fan to water. of course it must have a medium to leap through lah. since the fan is in indirect contact with the tank, it is highly possible to have a leap in this electrical energy field. (=

as for grounding wire. well. certain electrical gurus here told me that its useless to change it to those three pin plug types, as the original wire doesn't have the grounding wire attached to it in the first place. I don't know, I may have misquoted them by typing this. best to let them answer your question directly. (=

I experience that before. Is your fan AC type with metallic casing? Just use a screw to tie a wire on any hole of the metal part and the other end of the wire connected to the ground pin of the wall plug then your problem solved.

thxx Jun Hong will do dat ASAP.

The best option is to use a grounding probe, usually one made of titanium so that it will not corrode. You can diy one or buy one for about $30. Works very well.

Yup...I bought my probe from Pradiz Reef...User-friendly...after one diy guru changed it to a three-pin plug type for me...

[junyong84]

how does the ground probe work?

[hoppinghippos]

ground probe is simply having any metal in contact with the tank water which is in turn connected to the ground pin of your wall socket. but of cuz you need to use non-corrosive metal.
