I've been using Phosban for about two weeks now.  I've had a pretty bad hair algae problem for a few weeks now and since I've been using the phosban, the hair algae has stopped growing, has started turning brown and is dying off in a lot of places.  I admit, it's a slow process but it is working.  I didn't go with Rowaphos because of the whole sps bleaching thing.
