Dave, isn't that stuff crazy looking? I've never seen a Red/orange
algae in any of my tanks, for years and years, until late last year. It
slowly started growing in my African rift tank and covered
everything that was in the light path. My wife and I stood in total
amazement for several days as it grew and got very pretty. It had to
go, though, but still was the most attractive algae I've seen in a
home aquarium. I changed 25-30% for the next several days,
skipping a day between changes. Come to find out, my NO3, as
well as PO4, was a lot higher than I normally tolerate. NO3 levels
were ~ 50ppm if I remember correctly. In a week to a week and a
half, it was all gone, with no residual signs of it. The inhabitants nor
myself was very fond of harvesting it, so it must of left as easily as
it appeared. Enjoy it's added color while it's there, but like Paul
said, it's probably just an imbalance of nutrients.
