Full Version: Electric Shock

Just now I found that there is slight electical shock when I come to contact with the water in the tank. Later, found out that the heater is mul-function. After removed the heater the electical shock is gone. Surprise to know that the goldfish can take it. unsure.gif

Your fishes have not problem because they are not grounded.
As for yourself, your body acts like a grounding path for all the current leakages.

I heard differnt. But, I could be wrong. I thought it still hurts them. Low doses of current won't for a short period of time.

Then there is the factor of salt too. From the same idea of dropping electrical appliences into a bath or pool. If we could be absolutly certain that there was no salt in the water or your body you would be fine. But that is highly unlikely because you have salt and oils on your body.

Please correct me if i am wrong though. good.gif

Electrocution happens when there a return path for leakage current, the reason why the fishes have not problem is because before that all the leakage current are considered floating and will not do any damage (not return path to the ground.)

Unless the fishes touch anything conductive, in this case, like the hands of our bro Danny lor, then the leakage current will found a return path to the ground thru the fish via the hand and body of bro Danny.

And my advise to anybody adjusting any submerged equipement to put on an insulation media like rubber slipper or stand on a plastic stool. Just do a simple experiment, when you encounter the scenario described by Danny, just put on a pair of slipper, the stingy sensation on your hand will disappear immediately.

Thank "laser". I think the heater is with me for more than 2 years. Look like the time to change a new one also. sad.gif

Always invest in a good high quality heater to prevent this kind of mishap. Follow the instruction thoroughly too especially to switch it off and let it cool down before draining the water or removing it from the tank.

I have a few heaters and well, one cracked when I remove it without turning off the power. Tripped the circuitry to the whole house; luckily I have UPS for my computer but resetting all the timers (VCR, Microwave, Alarm Clock etc) is no fun!

Look for one with a thicker glass wall like those made by Rena (cheap & good) or Tetra. All the chinese brand can't make it. Oh yeah, I intend to discard my heaters after 1-2 years of use. The rubber seals by then should have harden and water could sip in.

Don't play play.

Actually there is another appliance that often leaks, thats the submerge powerhead. I know that it leaks when someone off the light switch in some part of my house ( where the fish cannot see ) and I notice that the fish ( a LH in this case )jumps/shoot ard the tank.

I read somewhere that you could actually dip a test pen into the water and see the bulb lights up when there is a leak, have yet to try it. smile.gif

Does the dipping a test pen method really work? Great, not only will I hang a thermometer on the glass wall, I can now have a test pen that lit up too. Cool man.

I guess the leaking powerhead/heater thingy is a good anti-theft device for your prized fish. rofl.gif

Or you can use my method. dip your finger in the water level.
If you see your hand automatically jump out of the tank. Than you know what is happen. yes.gif
Don't laugh I really use this method. So realistic good_very.gif
