    I wanted to add that I had a big green dust algae outbreak on the glass and I treated it by letting it grow for 3 weeks, lowering water line and wiping.

      I have the exact same algae, I believe its some kind of BGA, which is actually a bacteria rather than an algae. But honestly I am also not sure bacause I have seen many very different pictures of BGA over the internet. Unlike BGA, thiis stuff is only on the glass surface to the bottom near and under the substrate. Can someone really help us newbies out here?

        The algae in between the substrate and the glass is considered BGA by most, but I think its GSA as its generally sticky to the glass and you need to scrape it off with a blade or card and its only deep into the substrate to where the light bleeds. Areas not having any light, does not have this algae.
        I usually scrape everything to the substrate line and then I just inject some H2O2 between the substrate and the glass. It cleans it up and keeps it that way for a couple of week. I think its just not avoidable and I have seen a lot of setups with virtually no algae except that.

        Note that no one will tell you that they are completely algae free. As long as its not on the plants, everything else is ok.

          Looks like BGA to me too, usually has a particularly earthy smell to it. I've used Hydrogen Peroxide and Erythromycin with success before

            Thanks for the answers, and confirmation. I also started treating with H2O2 using a syringe, and it seems to be working so far. I unfortunately have no access to eritromycin, because it requires prescription by the doctor here in Turkey. Anyhow,I will see if I can get a prescription from our family doctor
