Beginnings of HLLE?

His coral beauty and purple tang both exhibited signs of HLLE while I was tanksitting. He has since switched to a different brand of carbon (I hope).

The carbon in question was black diamond and I had it tumbling too fast I think. The coral beauty has healed somewhat and the tang is fine. I am now running Marineland but have the reactor turned down enough so there is almost no tumbling.
