What’s coming off my hammer?

[bcournoyer5]

I found this string like material coming off of my hammer. I have attached a photo. I’ve noticed the hammer not being extended all the way towards the end of the night, and last night almost closed up completely. Nitrates are <20ppm and nitrite and ammonia are undetectable. I am going through a bacteria bloom as well.

The pic is really blue so my guess is Poop

It's expelling waste. Normal for most coral and euphelia
