Yep. It is well known on the Aquatic Plants Digest, for stopping algal
transfers. It kills all algae, but does minimal plant damage if done
exactly.
Start with standard 5+% sodium hypochlorite solution (ordinary Chlorox o/e)
and dilute it again by 19 parts water to one of bleach.
Tougher plants, like Anubias (the plastic plant that grows) can take a 3
min. bath in the stuff without serious damage. More tender plants may need
1-2 min. down to about 30 seconds for really frilly delicate plants, like
hornwort.
Rinse carefully, and maybe even hit with some dechlor (hypo) before putting
with fish, if in doubt.
I seriously doubt if any myco would survive such treatment.
