help i think i eletrocuted my coral

Only use pumps that contain a grounding prong.

if you have any chlorine remover add it, when electricity is passed through salt water it creats chlorine from what i have been told

An electric current is most likely to affect the fish first, invertibrates last. The more advanced animals with a central nervous system that are closest to the source are the most affected normally. Corals can close up for protection when things aren't going their way. If the fish are fine, the corals should be fine when you have everything corrected. The recommendation for carbon is always a good idea in such cases as stress can cause a release of toxins from some animals. I would look for more documentation on the chlorine removal idea. Cl- must be present to balance other major ions in solution in sea water and turning it into a powerful oxidizer with a little stray voltage in a tank seems to me to be unlikely.

Even pumps with grounding plugs put out voltage... I think it's from the magnetic fields in the motors. Each seems to put out 1 volt or so. Very strange - even the external ones. But, until you get your flow up around mine at around 10,000 gph, it's not enough to notice.

That would be induced voltage. Lighting in your open hoods produce the same induced voltage. That is what a grounding probe is good for. If you have a pump leaking voltage into your tank please replace it don't add a grounding probe and think the problem is solved. I am writing an article about this now, but I am waiting on a couple test before I release my findings.

Funny, I mentioned that once before about the pumps and stray voltage. I was told I was wrong.
