Before doing anything else with the mix, you should check the integrity of
the seals (bottle-to-cap, cap-to-tubing and any other there might be).
When I first set my system up, I got a short burst of activity then
nothing because of a slow leak in one seal. I went through a couple
iterations on the makeup of the mix, then found the leak.
If there is no leak, you might try adding some baking soda. I use a half
tablespoon in a gallon of mix. This seems to help regulate things (right
DWebb?).
