Too much CO2 kills bacteria?

Hello

Is there a possibility that by adding too much CO2 might kill off beneficial bacteria? When I say too much CO2 I mean within logical values that someone can pump into the aquarium e.g. 40 or 50 ppm!

Thanks
 
Well its been two months into my aquarium running now and I have lots of brown algae...

Personally i dont think there is much of a link between beneficial bacteria and brown algae. I may be incorrect though

When I set my tank up, after a month or two brown algae appeared, cured by turning my lights down by twisting the reflectors to block the light. Remainder was scoffed by Ottos. After a week or two lights back up to full brightness, no sign of brown algae.

Some people manage to run their tanks at way over 40ppm CO2 no plant, fish or bacteria issues.
