Hmm, diy co2 is pretty cheap to set up.. I'm gunna be seting one up next weekend. All you need, is a 2 liter bottle, some airline tubing, 100% silicone, sugar, water, yeast, and baking soda. I use the krib's recipee for it. Punch a hole in the cap on the bottle, just big enough for the airline tubing. Then, silicone it on. In the bottle pour 2 cups of sugar into the bottle. Add 1/4 teaspoon of baker's yeast and a pinch of baking soda. Pour in a little warm water (NOT hot) and mix around to dissolve the sugar and yeast. Then fill to the shoulder (just above the label on a soda bottle) with warm water. Shake well and cap with the tubing-cap assembly. Run the other end of the tubing into the aquarium. |
