DIY CO2. Can you use a valve to control amount?

[essabee]

I believe we can do more with DIY CO2. We can control input, timer and flow. This was what I was trying when I wrote http://www.plantedtank.net/forums/di...reservoir.html

For those still interested in entertaining this idea, has anyone thought of using baloons for storage instead of bottles??

Instead of controlling the amount of CO2 physically why not control it chemically? lessen your yeast in the mixture and you will produce CO2 at a lower rate and your mixture will be extended in it's life. The only problem is as with all DIY CO2 there is no precision in it at all just a limitation in the amount of CO2 created at one time. The exact amounts to use I have no idea because there are too many factors to take into account so there will have to be some experimentation with different amount of yeast. But the nice thing about controlling it chemically it won't cost you anything since you already have it all, in fact you'd be cutting costs in your demand for yeast.

That is exactly why I recommended using multiple smaller bottles who's starting times were staggered to produce a more constant average total CO2 output.

I think the staggered bottle is a great idea for constant CO2 production. Another thing could be to keep the bottles in a tub of water heated by a regular aquarium heater. The heater could be put on a timer to shut off at night and then turn back on during the day. This would keep the temperature somewhat constant throughout the day, even in the early morning and later at night when the ambient temperature drops.

Lol Epicfish thats what i said earlier.

lower temps = less co2 But you need to find out what temps yeast will die at and be fine at. ex: lowest temps, highest temps they will survive at .

Er, oops. Didn't read the whole thread. =)

Its fine
