I havent used the treatment myself - but a few guys over here that have had bad hair algea have, and had really good positive results with it.Haven't looked into it yet.
I've been hoping to avoid treatments and do it the natural way but I think I need to start considering them. It's just not going anywhere and looks terrible.
I'm not super worried about ich because I've had it a few times before and the salts seem to get rid of it. Will continue trying to just keep em nice and fat with food for a few more days and then might give it a go if I don't see any improvement.
My UV has been off for a month now, so that may be making a difference also!
