I don't either. Paul K. did and bleached his way out of it and
it's never come back (cept in two cases where he didn't sterilize
incoming fish or plants).

Ok, what's a desmid?

Nah, it looked more like a feeshwater sponge. Bulbous puffy slimey
birght bright merald green round lumpy things on the tips of some
Mayaca. I cleaned it out and it never came bacj.

Well yeah but they were the first ones to really publish "hey are

co2 - although I notice now JJ Scheel advocated CO2 injection
in the late 50s. He used HCL and marble.

It happens alright. There's lots of algae you can't see - slight turbitity
in the
water is in most cases under a microscope, algae and when all that dies, ammonia

It's the same warning you read on Aquarium Pharmecuticals Algaw Fix
which reportedy kills thread alage. That warning is there for a good

I have a couple.

I just diatom that once, change water and it's gone. I get it in new

That's higher than inverts can take. I think the secret to h202 is
not a big dose - 15 secodns of straight 3% did not kill anything
but black/red algae, thread algae susvived, but, so far 4 days at 60ppm
seems to kill off alage and leave even mayace unharmed.

Yeah, changing water before and after helps too.

I'd be happy to be able to put some paramters on the H202 stuff. I'm
still playing with that. One thing at a time :-)
