I don't know what kind I had but they started killing my corals and anemones. This worked for me in a 40g DT (55g system):
-Raised the pH with Kalk
-Black out for five days, I completely covered the tank with a metallic curtain (the ones that are like color in one side and metallic in the other). I added an air pump in the sump knowing the curtain would limit the gas exchange. Went back slowly, a week of just 2 t5 for 5hrs, then 6 T5s 5hrs.
-GFO, I used a cup of GFO with a little higher flow than usual and changed it every other day for a week and weekly for about 8 weeks.
- Wet Skimming.
- Absolutely zero water changes during the battle (about 8 weeks)

I think the key was being very aggressive with each approach, I'm not sure how aggressive you have been. Like the blackouts, not just the lights off but cover the tank and don't let any light in the display or sump and I did five days. The GFO daily or every other day changing large amounts and increasing the flow in the reactor a bit, not too much or you will pulverize it.
