I use about 1 cup sugar, 1 tablespoon of regular cooking yeast, and 3/5-4
cups warm water. The odd time I had the yeast blow over into the tank via
the hose so I decreased the water (we had a heat wave and the yeast went
into overdrive). This mixture lasts a few weeks for me. I've heard adding a
bit of baking soda helps extend the life a bit, and possibly prevent the
white fluff?

Good luck.
