    Hi,
    I have a 100 l planted aquarium that already had the cianobacteria algae problem.

    I added 250 mg Eritromicine per 100 l of water (without blackout of some days). I think the problem was solved, but now, after some plants added to aquarium and some weeks after, the problem came again.

    Now all plants have at least a "layer" of cianobacteria in all parts above the substrate.

    My question is:
    1) Do you know any better medication to add to this aquarium to remove that bacteria?
    2) Eritromicine again + blackout of one week would solve the problem?

    PS: I´ll anyway disassemble this aquarium because it will be set in another room, but i wouldn´t like to lose the plants. I´d first treat the plants and then move the aquarium.

    Thanks for your help!

    I had Cyanobacteria infect my tank for a year. I purchased Mardel Maracyn, dosed it daily (as prescribed on the box's directions) for an entire week with the lights off, and it cleaned my planted tank for good.

    I performed a waterchange, cleaned the filter, and removed as much as I could before I started treament. After treatment, I cleaned the filter and cleaned the tank again. It hasn't come back since.
