I have a bad cyano bacteria problem. I eventually used chemi clean last Thursday on my 150 gallon tank. Changed out 15 gallons Saturday and 25 gallons on Tuesday. My treasured magnifica is now bleached out as are four RBTAs. Strangely, two RTBAs are fine. Am running lots of carbon and gfo. Have changed out filter sock. Skimmer is collecting greenish yellow scrummate, pretty light colored. Any thoughts/suggestions, especially in salvaging my anemones?
