I have had the same problem for a while now but I have just (as of yesterday) gotten them to pulse again after about 2 months. It was a combination of things.
First, I am running a 90gal as well and have 4x t5ho lights. With that being said, They were near the bottom of my tank and were not getting enough light. Also my water was a little out. I do loads of water changes but I found hat my PH and my Alk were both low. Once I got my DKH to about 7-8 my PH was more consistant and now they seem to be happy again. Also watch how much current they are getting. Should be placed in a medium flow area I think. (Correct me anyone if I am wrong)
hope that helps. Might be a different problem yet but its a start.
