My two 2.5 liter Juice bottles only last me 1 week - after mixing with the help of Baking Soda, it produces too much uncontrollable CO2 bottles into the tank. I have tried using infusion set but the air host popped off the one way valve during peak production.
Is there any way that I can control the flow?

dont try controlling pressure in a DIY mix, the pressure may build and the bottle will xplod. it will stink up your room.
you can regulate the amount of co2 produced indirectly by varing the temperature. a cold environent will reduce the amount of co2 produced where as a warm one will increase production.
Hope this helps..

Try using less yeast.
That should reduce the volume of c02, and it should last longer that way.
What mix of yeast and sugar are you using now?

Thanks for this. I regularly mix 1/2 table spoon of yeast, 1/2 backing soda with 1.5 cup of sugar per bottle of 2.5 liters. I use two bottles in the hope of having long lasting supply. Should I change this recipe?

I use ¼ teaspoon yeast, a pinch of baking soda, and 2 cups sugar.

Yes, use more sugar, less baking soda and A LOT less yeast. When I did DIY CO2 I used less than 1/4 tsp, 2 cups sugar, 2 cups water, and a pinch of baking soda. Lasted 14-16 days.

3 parts water, 1 part sugar
skip the baking soda
pinch of yeast - it will multiply to cover the liquid layer with in a day or two. Should last at least 2 weeks unless your container is unusually stocky.

it really takes a good 75-100 psi for it to blow up......

Thanks - it works for me now with all your helps on the recipe. I turn my power-head off at night and excess CO2 escapes (I use baby milk bottle as a diffuser). Although all seem to be OK but I am facing one problem, my fish keeps gasping on the surface - is that too much CO2? How can I correct this problem?
I have tries some aeration using a small pump.
