Hi all,

I've tested glutaraldehyde in my aquarium for more than 10 months. The following picture was taken at 37th week of the experiment. But this tank was torn down and turned into NPT 5 months ago.



A few chinese hobbysists have tried high concentrations of glutaraldehyde to kill both algae and fish infections. The algaecide effects were positive, but the antibiotic effects were controversial.

Regards,
Erich
