Co2 levels w/out fish

If I have a fishless tank, should I worry about co2 levels? I mean, can I crank co2 to like 50ppm+ to jump start a tank for a month or so and then slowly back off before stocking? the 15-30ppm rule is just because of fish health, right?

thanks,

~joel

Lightbulb

great, thanks. Incidentally, I have snails in there, so I'll use CO2 as a snailicide.

I'm putting a 2 liter bottle with distiller's yeast into a 2.5g, that should be ridiculously high co2!
