Hmm...I don't know man...The thing with some algae is you turn off the lights for a few weeks and it subsides and you think it is gone and so you fire back up the lights, if you have one little spore in there it is quite possible and almost inevitable that it will begin to spread again if the conditions are right. I'm not trying to scare you, but I've experienced it before. I use to take all of my rocks out of the tank and scrub them endlessly until there wasn't any sign of algae on it and a week later, I'd be back to where I was! If the "problem" or whatever is fueling the algae isn't addressed, then you won't get anywhere. If you want to wait it out, then give it a shot. I know you have been fighting this for a while and it seems to be getting worse, but I'm sure there may be some things you haven't tried yet that may help. Hope you get it worked out
