Corals

Three main causes of bailout are:
Too much light and water flow
calcium low
Disease

Agree DKH way high- 8-11 is safe range

Hydrometer

I've personally never had a good experience with hydrometers, but to each their own.

What salt mix are you using?

I know people are suggesting things like polyp bailout or bjd, but again there are countless possible causes. If that alk number is truly 15 that should be your focus. It may cause a bailout for example or even as someone mentioned stress that leads to bjd.

Based off the browning of that skeleton though it seems this was not an overnight thing and the hammer had likely been unhealthy (and receding) for quite some time rather than a quick killing by bjd or an immediate polyp bailout. Unless it died days ago and the pic is just recent.

No. It was over time

 

[hunterallen40]

Do you have other euphyllia? How are they doing?

 

[mdb_talon]

No. It was over time

That rules out bailout or bjd and points to parameter or lighting issue as most likely cause. If you have an LFS nearby i would have them check your parameters. All the main ones but specifically alk and salinity. Sometimes regeants go bad, etc.

I had a war coral and it dies and I still have 2 hairy mushrooms

 

[attiland]

My green hammer coral disappeared.. any clues

Head bailed out. They are somewhere in your rocks but your chances are very little to save the heads.
sorry

And they have shrank also

This is generally an indication that something is off. What are you using for lights?

As stated above, I completely agree that you should have your parameters verified by your LFS. 15 dKH, 8 pH, 460 ca just doesn't add up. I would definitely check the expiration dates on your reagents.

How long did you have this hammer before it started taking a turn for the worse?

I've had it since May... Just started about a month or so

I just tested again
Cal 480
Alk 15
Mg 1470
Phos .47

 

[Sharkbait19]

In my bjd experience it was a few days or weeks of corals looking bad before finally giving out. The death/explosion is quick though. Not saying this was the leading cause, but likely a side effect.

How can I get my alkalinity down

 

[hunterallen40]

I just tested again
Cal 480
Alk 15
Mg 1470

Hm... That phosphate is quite high, and the alkalinity is beyond too high. Are you absolutely sure you're reading things correctly? That alkalinity is absolutely crazy high. If you're not dosing anything, I don't see how your alkalinity could get to that amount. Are you using RODI water when you mix your saltwater? Also how often are you changing water?

You can decrease with vinegar, but I wouldn't unless I was absolutely sure my alkalinity was 15.
