Default DIY CO2 factories -- how long do they pump?

I'm using a 4L jug (the "big" cranberry juice size), into which I dump most
of a 2Kg bag of sugar (about 4.5lbs) and a teaspoon of yeast. How long can
I expect one to last? I'm heading to Montreal for a few days, and don't
want to come back to a bunch of pH-shocked fish....

Thanks;
D

hmm, let's see, the normal recommended mixture is about a 1/4 to 1/2 tsp of
yeast to two cups of sugar and about a 1 1/2 liters of water and that lasts
me about 10-14 days. I'm not sure what is going to happen with your mixture.

Why would you do such an experiment and leave so as not to be able to
monitor it?

It won't last much longer than it would have with a normal recipe in a 2L
bottle except the CO2 production will be about twice as high for the first
week or so.

Actually I simply renewed both jugs -- I'll be back long 'ere they'll run
out. I'm still curious to know how long to expect them to last, however.


Cheers;

As already stated, probably no longer than the standard size- 10-14 days.
The extreme mixture you've made has no advantages that I can think of.
You're just wasting ingredients. The standard mixture was arrived upon by
comparing info from real-world situations by novices and experienced
aquarists alike. It's the best blend of quantity vs. quality.

The limiting factor, AFAIK, is the alchohol production by the yeast.
The commonly used mixture is about the max amount that can be used
before the yeast are killed off by the alchohol levels - any more and
it's just wasting sugar.
