Is Stray Voltage Killing my Coral?

[that Reef Guy]

Somebody mentioned that Stray Voltage could be killing my Coral.

They get stressed out whenever I do a water change.

Zoanthids Close up
Acans Close up and spit out white/gray matter
FrogSpawn / Hammer Close up and have the White/Gray Matter on top of them.

The other thing different when I change my water is I turn all my equipment off and then back on until the next water change.

I noticed both my Power Heads were making a loud grinding sound when I turned them back on.

My digital thermometer which is always saying 78.6 was saying that for a few seconds then saying 82.5 and going back and forth.

It stopped doing that when I turned off my Power Heads.

Is that what is killing the Coral?

I did not get shocked or anything.

I have been trying to figure this out for a while.

Please see my other thread to see what I have been saying about this.

have you checked for stray voltage, it is easy to check with a volt meter. when you do water changes do you try to match water temp and salinity to your tank if not that will stress corals

Where do I that?

How much are they?

Everything is matched up when I do water changes so it is not that.

Anybody think that Stray Voltage is the problem?

Grounding probes are like 10 bucks. You should have one regardless.
