[Killietalk] cyanobacteria

["Edd Kray" <edd at catfishnthecrawlers_com>]

Success fighting this stuff (cyanobacteria) at last.

I've found two methods.

1) (pretty extreme) A friend from the ALA recommended I empty the tank of
fish and plants and add one cup of bleach per ten gallons. Yup, it gets rid
of the cyanobacteria COMPLETELY in about five minutes. Let it sit that way
for a day and then change water, change water and change more water till the
bleach is gone. Of course you need to re-establish your now dead filter but
it got rid of the cyano'b and it hasn't come back. Take your sponge filter
out (I didn't) the bleach just destroys the foam they use in "Dirt-Magnets".


2) Less extreme. On another tank, I used Maraycn (Erythromycin), one tablet
per ten gallons. Let sit 36 hours, then change 50% of the water and do
another dose. The tank is now clear of the ugly stuff and I didn't even have
to remove the fish and plants.
