    Black out... it wont fair your plants well, but its a sure fire way get rid of this. Simply shut out all light from getting to the tank by covering it with a blanket.

    2 weeks? Usually what I see is a blackout that is only recommended for 3 days.

    We need to address the root cause.
    What kind of lights?
    How long are they on?
    How many nitrates?
    How much flow do you have?
    Tank size and stock?

    I would do a 3 day complete blackout taping black plastic bags arond the tank to ensurevno light at all can get in. As mak said you will also need to fix the root cause so it doesnt come back

    depends on the severity, its worked for many people, 3 days-week is fine for a small out break, but the less time that the tank is blacked out, the more likely it is to come back, however I do agree with that we need to know the variables of what maybe causing this

    They are on for 10 hours a day
    Nitrates are 15-20PPM
    Flow is about 250 GPH turn over (1 Power Head, 2 Filters)
    C02 (Just started dosing Seachem Excel yesterday....)
    Ferts Just started using Seachem Nitrogen, Phosphorus, Potassium..
    Tank Size is 10 Gallons heavily HEAVILY planted.... and Cardinal Tetras.

    Reduce your lights to 8 hours at most, and manually remove as much as you can. Keep nitrates up, and do a 3 day blackout if it keeps coming back. Antibiotics or peroxide can be a last resort.
