Re: [APD] Black brush Algae
Here is a link to one person trying Excel and a cheaper substitute on his
BBA at the Aquatic Gardeners Association Forum
I posted in there about a person I know using standard commercial 3%
Hydrogen Peroxide on his BBA. I also seem to remember someone using H2O2
here a few years ago. Could it have been Vaughn Hopkins? I didn't search the
archives to check.
BBA is found worldwide in natural streams. It is eaten by Gammarus and other
organisms, but never to the point of complete removal. The holdfast remains
and the BBA can regrow from it. I think this may happen with SAE too. I once
had SAE and they did eat the BBA, but only if I didn't feed them other food.
I didn't really see them as all that effective.
Here is a link to a photo of BBA I took at work.
(I hope it works) The scale divisions are 1/64 inch or 0.015625 inch. This
is a piece that was free floating in my aquarium. I determined it came from
plants I was given that came from a tank with BBA in it. The holdfast is in
the center and it is attached to a dead hard plant part or stick goes off to
the right and downwards (has an air bubble).
I have tried to grow BBA in this tank by adding gravel with BBA on it. I
wasn't able to see any BBA in the tank after 6 weeks had passed. I removed
it when I thought I saw BBA starting on some Cryptocoryne ciliata. I threw
out the infested plant and the gravel. I didn't look closely at the Crypt at
that time though and now suspect it was Compsopogon, (Staghorn algae), which
appeared in the same tank a few months after the first appearance.
Here is a link to the Compsopogon I took at work
The pointer is about 1/16 " in diameter. I was using it as a weight to hold
the leaf down and under water.
