Nolvasan is a “brand” name for Chlorhexidine, as distributed by Wyeth and Ft. Dodge Pharmaceuticals. You can obtain it for about 50% less in the generic form, without sacrificing efficacy.
While Chlorine and Chloramines may be present within most municipal water supplies and public pools, there is some valuable European literature regarding the negative impact such chemicals have upon hereptofauna. I actually treat drinking water, for my animals, with a product known as AmQuel, which removes chlorine and chloramines.
Copperhead, you indicated you “used” to work within a bio research lab, I would have to ask how long ago that was, as my wife is “currently” conducting research within a secure infectious disease laboratory, where they work with some truly nasty pathogens, and as I indicated earlier, they have abolished the use of bleach, due to the physical and environmental hazards it has been known to cause. I too, have abolished the use of such within my lab as well, due primarily to the findings of the ID lab my wife works within.
Bleach may be effective, but in light of newer, safer and equally effective products, I still feel as though the use of such is “old-school”.
Also, as Bill has indicated, Chlorine is useless in the fight against Cryptosporidia serpentis, as only ammonia, UV radiation and heat are known to be effective in the fight against such.
All in all, I really do not believe there is a single correct way to properly clean and disinfect enclosures and I know a lot of folks still use bleach, to no ill effect, but there are safer and equally effective ways to accomplish such…
Best regards,
Jeff
