Stray Voltage affect zoos?

[Tripspike]

I got a small shock the other day when I put m hand in the water. The shock occured as my cuticle hit the water at a small cut. This is the first time this has happened. I have a rrather large colony of green zoos on a rock which had been doing fine for quite some time. 2/3 of the zoos are not opening now and they are starting to look funny. Will stray cureent cause this. Will post some before after pics soon. I fragged off some good polyps and inspected the rock. I removed a few astrea stars...not sure if they were causing problems..

Thanks for any input,

Trip

Most definitely it will. We had a great debate here locally a few years ago about this. I have always used a Grounding Probe in my refugium to prevent stray voltage. Stray voltage has a direct and adverse affect in the short and long term. Some have said that a GP does just the opposite and creates stary voltage, I totally disagree. I can't remember the gadget I borrowed from a friend at work, but I think it was called a volt meter or something of the sort, if I'm wrong on the name, I stand corrected. I tested the water with and without the GP, and yes, the GP made a major difference as many of my corals were retracting 24/7.

Having a GP is both a reactive and a proactive approach to resolving the stray voltage issue, but care must be taken to find the root cause of the stary voltage. Through a process of elimination, by unplugging everything one at a time in my tank, I was able to isolate the culprit. It was a simple powerhead that was leaking stray voltage.

Some say there's no such thing as stray voltage. Some have said a grounding plug will do even more damage. What is your opinion? Do you have a GP?

I don't have a gp but I have never been shocked either so I see no need for one yet but it would depend on the amount of voltage being leaked into the tank some people say a little isn't a concern. As long as the inhabitants of my tank are happy I'm happy
