Corroded wire causing melting?

[GatorScott]

So for a few weeks I’ve racked my brains trying to figure out why my Zoas were closing and disappearing. I’ve searched high and low for pests, and been trying everything in the book to figure it out. Long story short I gave up and just accepted them disappearing. Then last week I found my temp probe had corrosion coming from it. I pulled it and since they have stopped disappearing. And a few colony’s that I have thought were goners are now opening back up and growing.

Is this a coincidence or was the corrosion causing it?

It's possible. Yes

It's possible. Yes

Any idea why it would have affected some Zoas and not others? Also LPS and nem showed no signs or anything negative.

Nope. Save some species apperanly have different tolerances to things.
Sps to sps or zoa to zoa it seems

I lost SOME of the sps here.
Warning. Pretty graphic coral death.

Crazy how that works. I literally tried everything and stressed and stressed. Then got to the point I just said forget it and accepted it. Now they are growing back lol. Such a rollcoaster.

Yes it is. So far I only run Rox 0.8. All is back to normal and hope it stays that way. Thanks for the input.

Maybe there was iron coming from the corrosion. Iron absorbs phosphates, low po4 causes them to close. Have u measured po4 in that period?

That’s probably what was going on. I know it’s sad to say but I never test anything other than salinity and nitrates
