Hammer not opening fully

[temnich23]

My hammer coral hasn't opened up fully for the past week. I had a bit of an issue where I used too much 2 part reef putty which stripped the oxygen from the tank. Levels are back to normal. I'm still feeding daily. Does it look healthy?
Thanks

It's not super bad. My hammers get like this after lights go off. What are your parameters?
No body will be able to help you unlessnthey know what your parameters are.
Any 'reef safe with caution' fish in the tank?

Those are my last checked parameters. I have a small bi coloured blenny in the tank but he doesn't bother much with the corals.

Alkalinity? Have you done a water change recently? How much flow is it getting?

 

[temnich23]

Alkalinity is 10, I did a 20% waterchange yesterday. I have an ai nuro which is placed above the hammer as seen in picture

Your parameters, light and flow look ok. May be little more nitrates won't hurt. And I won't consider your hammer unhealthy. My hammers n torches act like this when I change something suddenly. Like accidentally turning off light or increasing flow quickly. In QT they looked like this after every water change becuase QT tanks volume was just 26 liters(~7 gallons)
I would keep an eye out if the condition goes worse. Also keep checking the stem part for excessive dark color stuff.

High phosphate did that to mine, you may want to look onto getting some marine live rock for your tank as the one you have is ocean Rock and not suitable
