Why??!!???

[Havok1071]

I have a beautiful hammer who is just shedding away.....I don’t understand why. He has been doing amazing for months!
nitrates 10
Nitrite 0
Ph 8.0
Calcium 450
Magnesium 1600
Alk 9.5
Any help would be appreciated.

light, flow , stability, parameters disease, one or all

polyp bailout, and I agree it could be many factors but is caused by some form of extreme stress.

The pics are too blue for them to be helpful. All pics for diagnosis should be under white.
You post no phosphate number.
You need to keep (and maybe just didn’t post) phosphate in the 0.03-.15 area or corals will slowly starve. Your nitrates are fine.
Your MG is too high, should be in the 1260-1360 range, let this deplete over time.

Your Mag is high and other factors that will cause this is:
Excessive white light
High water flow
High ammonia
RTN
Fish such as butterflies pecking at it

Do you feed them 2-3X per week?

Sadly euphyllia can do that even when everything in the tank seems to be doing fine. Couple of things you could check outside of what was mentioned above. Water quality, are you using rodi water? Pests on the skeleton, though it doesn’t look like you have any other corals by it sometime corals stinging one another.

I feed them once a week with reef roads. Should I up this to twice a week?

I do a 10% water change once a week and do a RODI top off as well. The only thing I can think of is my engineer goby building up Substrate around it,

That shouldn't be an issue unless it was kicking up sand from the substrate and somehow getting into the mouth or maybe detritus build up when there is a lack of flow. I've sadly had euphyllia melt of all the reasons probably listed above. Frustrating and saddening...

i never feed mine...never! and they grow like weeds.
