    hi sorry but i'm not a guru here but since no one else is available at the moment, I think I can try to help a little.

    For the walls definitely is use some manual scrubbing and then do a major water change. For me, I would turn off my filter while I scrub so that the algae would not get stuck into my filter medium.

    For the plants, I normally scrub them if I could (only possible with some plants like nanas) outside the tank.

    If it is not possible to scrub the plant example mosses, I would use a diluted bleach solution. Pop the plant into the solution and shake it for about 1-2 minutes. My moss normally comes out looking greener. Neutralize the bleach on the plants with water mixed with any water conditioner. I dunno how long to soak the plant with the water conditioner, but I normally just leave it in there for at least 20 minutes whilst doing other stuff.

    Not sure if what I am doing is right, anyone with more experience please correct me.

    Time it with your water change regime.
    Go through the lot with your fingers (I find this method best to not hurt the leaves).
    When you're done with that give the tank some current or make some so the stuff swirls.
    Then start your water change ans siphon it out.

    Siphon off the dead BGA as much as possible. Otherwise they would cause a nitrogen spike and the next algae to appear could be BBA.

    BTW - how did you kill off the BGA? With antibiotics?

    I used bleach solution method to kill the algae on the plants, even the mosses. I used H2O2 to clear the walls and did some scrubbing too. But it is the plants that is really suffering from the dead BGA.

    Ive done a thread on BGA some months back, my experience with dead BGA = difficult to remove, so much so dead BGA => new regrowth BGA after 3-4 weeks. Best way is water changes every 3 days.

    Finally cleared it to a great degree and the solution is the most interesting one too...oxygen. I noticed a great deal of my fauna were struggling to stay alive, so I suspected that the decomposition of the dead BGA was creating a surge on CO2, so I placed an air pump and a basic sponge filter. In a few minutes, my fauna was alive and kicking with no sign of stress. In a day, I noticed my BGA was clearing up alot faster too. Sorry I don't have any pics to show you, but it might also be coincidental that the dead BGA started clearing faster after introducing an air pump and I really didn't have a hypothesis on why it is so, just a nagging hunch that should be the way to go.

    1) oxygen doesnt clear dead BGA. 2) dead BGA doesnt = co2.

    Since decomposition is primarily caused by bacteria, doesn't decomposition of any organic material release CO2?
