I looked in my tank today and saw 3 or four "tufts" of white stuff growing on the underside of my driftwood. It looks more like cotton then any algae I've ever seen. The SAE seemed to enjoy eating it but I wasn't sure if it was safe so using my hands I removed it. It all came off in one piece bot had to be sort of "rolled" off. Also it's only one one piece of the driftwood. Each tuft is no bigger then say a dime. Any clues?
Thanks
