    the smaller head on my hammer coral looks really weak and is not improving no matter what I do. I have tried increasing calcium doses and water changes. Any help help to get it better would be much appreciated.

    You might try changing the flow around it.

    Is your lighting ok?

    Lighting? Flow rate? In my experience, hammers generally do best with a low flow rate. This allows them to really 'open' up. That little bunch may just still be exactly that, little and not yet ready to blow up. I position my hammers in the middle of my aquarium and use 1 single current usa LED light.

    My hammer has been by far my biggest surprise in regards to growth. I started with 1 small bunch 4 years ago and now have 4 MASSIVE sections. I add ZERO supplements to my tank. I'm not denying they may help, but in your case here, I doubt lack of dosing is the issue. The video in my signature has some good shots of my hammers opened up and full if you are interested.

    To recap - low flow, middle of tank, medium light.

    Good luck!
