High CO2 is making Algae?

    I use this as my co2 reactor. http://www.aquariumplants.com/cgi-bin/cart/pr374.html. I find it very strange that inside the chamber is my highest concentration of a black or brown algae. BBA I think. It grows like wild in there. It almost seems like it loves the co2. The plants right around the output of the reactor also I have a lot of the black stuff on them.

    The whole aquarium is starting to get it. I prune off the most affected leaves. But at the rate it seems to be growing I will have nothing but stems soon :( Not really the plants seem to be growing well but there is a lot of this stuff.

    I have been keeping my PH at 6.7 to 6.8 during lights on. KH of 6.5 -7. I turn off the CO2 at night PH in the morning is about 7. I turn the CO2 on about an hour before the lights come on. I have been dosing 1/2 teaspoon kno3 and 1/16 phosphate and 4ml trace twice a week. Changing 50 percent of the water each week. The tank has had plants in it about 3 weeks now.

    Any ideas on how I can get rid of this stuff? I just put a power head in the tank to direct the water away from the reactor. I also put the reactor a bit lower away from the lights. I dunno if that will do any good though.

    Thanks Rick.

    Simply clean it once a month or so.
    Dip in a 1:5 bleach solution for 15 min.
    Algae will build up in those if they get light.

    So you will need to clean it, it's not due to high CO2 though....

    Ok Tom I will continue to clean the reactor. The same brown gunk, bba or diatoms maybe is also getting on the plant leaves. Can I concider that normal too or do you think it will stop as the tank matures and I use the EI method?
