I think the biggest thing that helped it was when I started dosing the BRS 2 part system. As soon as my Alk, Mag, and Cal were in order, and I learned what to dose daily it really started coming back to life. I also monitored it daily and learned what kind of light and flow it wanted. At first it would only come out in the darkest areas of my tank. I literally had it placed in one of the caves for a few months. As it started growing more I began to creep it out into the light and flow. It now sits in the same lighting and flow as my other hammers and frogspawn as perfectly happy and growing faster than ever.
