I know Redsea has diff trace elements for diff coral colours.

I do enough water changes for that but I also do use Red Sea products, plus starting back on my Prodibio routine, so will be adding amino acids from them after lowering the nutrients.

I purchased some frags from a guy that ran 10K metal halides, in his tank they looked "ok". On the day I brought them home they were bright and growth tips were crazy. After a month in my tank the colors weren't quite as impressive and growth tips receded. After a while (several months) the color and growth tips seemed to recover significantly, but not to their original glory. I've had some corals get much nicer under the T5's as well.

Yes thats interesting. I thought of that also.

Agreed. Mine are over 3ft. 50g. I originally switched to T-5 to get the better colour many were reporting.

Two words before I get burned at the stake.

Supplement nitrates.

What are your phosphates at? Doesn't really sound like a bulb issue
