    Hi,

    Im piotr, i just subscribed for a year and cant wait to read the reports.
    Now that i have acces to the algae control forum i would like to ask you guys (and girls?) a question.

    A little branch of my driftwood is softer than the rest of the wood and it has some black brush algae on it.

    The tank is a no rush, no co2 low light kind of tank as this really suits my life right now.

    The wood came out of a different tank that i neglected for months, the algae started in this old tank, not in my current one.


    Is it ok to just leave the algae on the wood? is there a danger of it spreading onto the plants?


    Here are 2 pictures to clarify things.

    The algae is on the end of the high branch almost breaking the surface.

    Thanks for reading,

    I'd kill it with Excel or H2O2 during a water change/or tunr the filters off for a minute, then spot treat.

    Thanks for answering,
    would Easy life Easycarbo also work since it is a liquid carbon source like excel?

    2 ml. per 50 liters per day.

    Ah the info came to me instead :)

    For how long should i keep this up?

    Should i slowly decrease the amount of carbo over a couple of days (after the algae is gone of course) or is it ok to just do a sudden stop?

    This is not going to take just a few days, more like weeks. When the algae colours red or white it has died. After that it will detach in a few days. Then you can stop.

    I was not counting on it taking a few days, i meant should i be decreasing the amount of carbon after the algae is gone or can i just stop giving the carbo immediately?
    (nl: moet ik de dosering afbouwen, verspreid over een paar dagen, of kan ik van de 1 op de andere dag gewoon volledig stoppen met de easycarbo)

    I can imagine that the plants get used to the carbon and that maybe they would suffer is suddenly i stop giving it.

    I appreciate that you translate for me, but I understand what you mean ;) I was just giving you an estimate on how long it takes :)

    With a non CO2 it's better to decrease the amount slowly, you might even ask yourself if you want to stop completely. Continuing with 1 ml. per 50 liters per day will give you better plant growth and less algae.

    The translation was more for myself to check if that was really what i wanted to say :p

    I will decrease the amount over a couple of days, thanks for clarifying that.

    I know i will get better growth if i continue with the carbon but one of the reasons i started a non co2 tank was so that i dont have to add anything daily.

    Once maybe twice a week thats okay but daily? no, not for now atleast.

    No, twice per week does not help because Easycarbo degrades fast. That way the plants always have to change their enzymes. This will inhibit good growth and still cause algae.

    I know, thats why i dont want to use it. i was just saying that adding whatever is perfectly fine as long as i dont have to do it everyday.

    If you are using it to just kill BBA, this is fine(one time use), but peroxide is much much cheaper than Easy Carb and can easily do the same thing.

    9 days of easy carbo later and the BBA is getting noticeably weaker. I did however discover some (thread??) algae on 2 bolbitis leaves that are most exposed (Highest place and right in the middle under the lamp) to the light so today i took out the reflector, anything else i could do that would help? Oh i also added some PO4 and NO3 (0.5ppm PO4 and 8ppm NO3)

    spot treating will kill whatever BBA you have within a couple day. the BBA will turn pink, then gray. Then it will disappear or be eaten by shrimp. The best way to spot treat is to lower the water level to expose the branch. Then use a syringe and inject glut onto the BBA directly. Wait about 5 minutes, then fill the tank back up. Bye Bye BBA.

    As tom mentioned, you can also use hydrogen peroxide.

    This is a good article on non-co2 methods:
