Electrocuted The Tank !!!!!

[auqua man]

Wow did I ever mess up. Around 6 months ago I tryed to hook up a chiller to my 110 gal and realized that a electric current was present in the tank. So I, after some head scratching figured out the house had no ground. The house was wired in the 50`s so I decided to upgrade for " SAFETY " not the tank of course. So I sucessfully upgrade some of the electric in the house and move the tank power to the grounded circut. Ok here comes the dumb part I later added many more items to the tank and it always seems I am looking for MORE power. So I decided to use a non grounded plug to power the lights in the sump. No problem right but I then for some unseen reason I pluged in a electric power cord to my seio power head in th same outlet. so for the last 3-4 weeks my tank has had some strange things going on, now it all makes sense. At least I did not loose any live stock yet. Oh well live and learn. Maybe santa will bring me a ground protection for Christmas:lol:

That should have nothing to do with it at all Aqua. Half of my stuff was one or the other with no problems.

I have good water quality I think mag 1360 pm cal 450 kh 9.6 ph low 7.98 ph high 8.18 the swing is a bit smaller normally nitrate 0.1 Phosphates are undetectable . I recently hooked a refugium up to the sump, lights on at night.I have some bleaching on my soft corals?? thought maybe the power thing could have caused it. The only other thing I have changed is I had some algae on the rocks so I stoped feeding bio plancton for a few weeks to see the diffrence. Algae is gone.
Boomer did you have current in the tank?

You can not go but that, if you are talking about taking a VOM and sticking a probe in the tank and the other end to a ground screw on a wall socket. If you do that and it reads like 20, 30, 40 or volts that is not real voltage. If it reads high like 90, 100 then it is. We have had many discussions on it here. Do a search on Induced voltage or GFIC.

All tanks will show a false current as the cables, motors or even nearby equipment puts out an electrical field which the VOM thinks is voltage and it is not.

Here are some to look a

They do not work for me either. You have to copy the address and paste it into the browser.
