The two most commonly-reported aggravations stemming from yeast generators
can be eliminated very easily with the use of an extra bottle of water.
Simply use it as an in-line water filter, bubbling the CO2 through an air
stone at the bottom of the bottle and bleeding the filtered gas off the top.

All of the nutrients, volatiles and aromatics along for the ride with the
vapors get trapped in the water filter rather than your tank. No more
cloudiness, no more white "slime" at the tank's output.

Amazingly enough, in a bottle of clean water the "slime" doesn't seem to
gain a foothold on the air stone the way it does in a fertile aquarium...
