Help needed - electric shock

joelat · Apr 15, 2023

Hi everyone, recently I had encountered a problem with my tank. I was getting stray voltage in my water from one of my pumps. I have replaced the defective part but since this has happened none of my corals have really opened. Before this happened I was seeing really nice growth and extension.

has anyone had similar before? If so, is there anything else I should check or will they be closed/unhappy for a week or so?

I would check parameters etc. I asked several times for proof that stray voltage causes issues and no one provided any. My reason for asking is because people keep saying stray voltage causes deaths in our tanks and that just has not been my experience. I had 2 hydor koralia powerheads leaking. I would get jolted when I stuck my hand in the tank. I measured 48 volts in the water and all inhabitants, corals nems and fish showed no abnormalities at all. I replaced the powerheads of course, after falling off of a chair when I got shocked. This proved to me that stray voltage is a non issue. JMO

While assuring levels such as phos, nitrate have not become elevated, assure alk and CA have not dropped. Corals are not grounded and should not have become shocked but there is something with water likely occuring

I had a similar issue ,not a Great experience getting a belt when cleaning my glass .seems coincidental that all corals have closed since this issue?

could it have been due a reduction in flow or could it be copper poisoning?

This was the test I had done after I found the fault

Nitrate looks a little high and phosphate should not be 0. Recommended is .1 PPM. If you are bottoming out your phosphorus the corals will starve. Basically you need both phosphate and nitrate in your system, it's a little more complicated. As for your corals closing up after equipment failure, if you had copper and other metals exposed sometimes they can leach contaminants into your tank.

Is the best cause of action here to do a water change and dose phos?
