co2 system help

[uberunce]

is there a way to slow down or turn off a diy yeast co2 system without losing any co2 created in the 2L bottle or having the bottle explode?
i read that you should have the co2 system off while theres no lighting since it only works with lights on, thats why i ask.

umm u can have several t's to divert it to extra soft drink bottles or run a ball valve

Partially collapse the extra bottle so it doesn't over-pressurize and cause problems too.

Aquarium valves will work for this.

Biggest problem is remembering to do it!

Be careful, when doing my research for my build I found a TON of horror stories with exploded bottles. They ranged from stating the house smelled like Shiner Bock (mmmshinerbock) to raw sewage. I know my bottle sticks pretty wicked and I'd get devorced if it spilled let alone exploded. I just let mine run all night. No valves = no stink bombs.

you could also just run an air stone or two at night that will cause the co2 to gas out more resulting in lower co2

with a 2L yeast co2 system and an empty 500ml collapsed bottle how many hours do you guys think it can stay off for?

off? as in closed valve?

wouldn't recommend it at all. at least put a "T" valve in the line and just let it bleed off. You don't want this system under pressure.

How many bpm are you running on average?

from what i know i think most 2 litre soft drink bottles can take either 60 or 90 psi. ill have to see the psi they can handle. use multiple bottles and have a bleed valve on the last reserve so if it still keeps climbing you can bleed it off at a curtain pressure.
