    dear all,

    I seem to have some kind of algae/bga/gda infestation in my tank. the problem is that I do not really know what it is. on leaves, it feels a bit slimy and it can be partially be rubbed off. when you do that in a bowl, you get green water. it also grows on the flourite black as well as on the glass. within 2 days I see a film of this algae.....
    It does not seem to be green dust algae since I was on vacation for 3 weeks: the glass was covered with this algae, I removed it after the 3 weeks together with big waterchanges, but within 2 days it was already growing again. So, nothing of this 3 week cycle which seems to be a popular method to get rid of gda.

    any idea??




    greets,

    I grew some algae within 3 days on a coverslip that I placed in the tank. then, I took some pictures with a microscope:

    Wow, from your first post I would say it is green dust algae, which can take more than one 3 week growout attempt to get rid of. Surely that microphoto will enable some of the experts to identify it exactly. If Tom is back, I'm sure he can do so.

    oewh! tom writes..... he is back!?

    in any case, according to the "all knowing internet", gda seems to be a Ankistrodesmus species. when I google I only find needle shaped structures. very different from mine. So no GDA?

    Any way, I thought to give it a bump... (and tom sees my post sooner...)

    thanks anyway VaughnH!
