I wouldn't call it an "algaecide"......the colonies of "good bacteria"
compete with the algae for nutrients and in effect "starve" the algae. I
suppose it works the same way as plants competing for nutrients that then
starves the algae.

the "beneficial bacteria" that comes in powder form or in the pouch
that
goes in artificial flower dispenser. I used it with much success
atcontrolling algae last summer. My question is: does the water have to
bewarmer for it to work or can I add it now and try to avoid a spring
algaebloom?

I have never heard of a bacteria that was an algecide..... I would like to
hear
more about it. It has been my experience that the bacteria only work on
the
mulm, and other "dead" organics, not live algea.....what type algea did it
control? Jerri
