sounds like what happed to mine... im no expert by far but this is what i did
this is what it looked like
having lost the first one the very same way i had a bunch of pals come over and rush about helping me to save the second one.. this is what they did... it worked for me but of course you will have other advice,and you should use your sense as to what you should do
the hammer was removed from the tank and placed into a bowl of RO water ( unsalted) for about 5 mins( so that any parasites would wriggle out)...then a small quarartine tank of salted RO water, with a small powerhead,heate ( i had to microwave the water as i was in a hurry)r 11w lighting ( i did at the time have an issue with nitrates but they were all confident that this wasnt the cause)
after 3 days - i was delighted to see the hammer looking like this ( in Q)
it had indeed made a full recovery.. then i went up to scotland for 3 days.. came back to find someone had trurned off the heater by accident
so after all that i lost it anyway ( it was past saving when i got back and no one had noticed
)
like i said im no expert but the guys that helped me have over 50yrs between them experience..and as you can see it worked for me...well till i went away!
i think its a bit late now for the usual posters to be on.. but get as much advice as you can.. and i wish you all the best i was heartbroken when i lost mine, they are what i loved about marine.. what i wanted more than anything
