After many years of running a planted tank I had an unfortunate and complicated "CO2" event that wound up resulting in a terrinle algae problem. I had real problems with hair algae and an algae that I believe is called blue green algae and actually a form of cyanobacteria. In any event, this led me to redo my tank and at that time started using dry ferts in an EI dosing routine. I replanted many of the plants in the tank and they looked downlight nasty with the algae seemingly still thriving. New plants that I put in at that time also began to suffer. This killed a good portion of the plants in the tank, but I was told in these forums to keep doing exactly what I was doing with only shortening the photo-period of my lights because I do have rather intense lighting. This ultimately paid off because after just about 2-weeks, there was new growth from the plants including ones that were covered with the blue green stuff. Once that started, the new growth has been beautiful and the algae abated completely. I cut the new growth off, discarded the algae-covered stems that were rooted and replaced them with the new growth,
I've been reading threads here that address algae removal because I find the idea intesting, though I no longer have the algae problem and someone had posted this page that you might find interesting....I havent done it but there seems to be a lot about this idea in the forums:
