0.3 volts in tank.

Oh, glad to hear that you aren't having problems.

I don't believe that there is an issue, but there are probably some here that may disagree. I live by the rule of "If it isn't broke (or having problems), then don't worry about it..."

 

Everyone has their opinion about probes. Whether fish feel it, b/c they are not grounded and so on and so on. The main reason to put one in, along with a GFCI is so you won't hook yourself up with a nice shock. I was getting voltage on my meter and the reason I noticed was that I could feel it (14v) when my skin was touching the water and a ground at the same time. It is definitely a worthwile investment (15-20 bones) so you wont light your assets up. Just put in the sump to satisfy the argument of having voltage transmission through the water where fish swim. Good Luck ;D

 

wait... i have no idea what you guys are talking about with all this voltage stuff and what it means but from what jackerma just said, is this why when i was installing pumps the other day the water literally shocked me? like i was about 1 cm away from the water and it just shocked me out of no where. Never seen anything like it. Kinda hurt actually! haha

 

At such low voltage it seems to me like faulty equipment is not the cause. More likely induction from something.

 

When you killed the power to the tank, did you just hit the rocker switch on your outlet, or did you unplug it from the wall? I would completely unplug it, including the lights, to see if you are still getting stray voltage. If it's still there, test your meter. If it goes away, you will have to plug the tank back in, then unplug each device one by one to see which is causing the voltage. Either way, I would get a grounding probe and be done with it.

 

I want to see an answer to this. please

 

If there was that much voltage to arc and "jump" out of the water, there is a serious issue in one of the pieces of equipment. I would like to know if there are any direct power pumps used in the tank, like an AC powered pump. AC is generally what you feel when you get zapped and it hurts bad. DC will give you a slight tingle, like when you lick a 9V battery terminal.

 

oh let me be the first one to point this out. Volts are always in the water! And they are harmless!! Its an amp reading that would kill everything. There is a long thread here somewhere by an electrician. Let me see if i can dig it out............
