another diy CO2 question

How long should a CO2 batch last? I made a batch last week. And the bubbles are starting to slow down. Ill put my rescipe i used.

In a 20 0z vitamin water bottle
1 cup of brown sugar
1 table spone of yeast

It was orgianly about a bubble per second now its like a bubbble every 1.5 secons after a week. How long should it last?

Try using 1/4 tablespoon or 1/2 tablespoon of yeast instead of a full tablespoon.

I notice filtered water helps quite a bit.
