co2 DIY slowing down...when to change bottle?
I dissolve the yeast in warm water before adding. I should qualify that I
use 2 cups of sugar initially in a 2 liter bottle, and I'm sure the amount of sugar present determines how successful the additional yeast will be. If the bubble rate doesn't increase within a few hours, then it is probably not going to work for you. It could also depend on the type of yeast used. What works in one recipe may not work in another, but it's worth a try. Jody "Dave M. Picklyk" wrote in message ... Jody, I've taken your advice and added another1/4 teas. of yeast to my mixture (I first dissolved the yeast in a tad of cold water before adding it to the bottle). I've sloshed everything up a bit in the bottle after replacing the cap to mix it up. I hope that won't slow it down any temporarily before it starts up again. How does it usually work for you on the second 'charge'? And how long will it go for again? (I have 2 cups of sugar in my mixture) thanx, Dave. "Jody" wrote in message news:dbj0a.274$cz4.131@FE05... You can't do it indefinitely, but doing a second 'charge' has worked for me. Jody "Jim Miller" wrote in message ... iirc the problem is that while producing co2 the other output product is ethanol which starts to poison the yeast. diminishing returns... jtm -- Remove NOSPAM for email replies "Jody" wrote in message ... Well, you could try adding another 1/4tsp of yeast and see if you can keep it going another week or two. I would say 4 weeks is the max you will ever be able to get. Depending on the size of your tank, two bottles going at once via the T connector might be too much CO2; 26ppm is pretty high already. You just have to use your best judgement on when to change. If you got an initial 0.5 drop in pH for example, and it comes back up more than 0.2 or 0.3, you might want to change it or recharge it as suggested with more yeast. Jody "Dave M. Picklyk" wrote in message ... My C02 DIY has been running for 9 days now at 26ppm, 7.1ph. Now the Ph has gone up to 7.2, meaning I have about 21ppm of C02. I have an airstone attached to the hose so I can't really count the bubbles but I believe the stream has slowed a tad. When should I hook up a new bottle? Or should I get one going now and attach a new one with a T connector? How much should the ph go up and c02 go down before changing? I don't any extreme changes to mess things up. Dave. |

I have been running yeast CO2 for years - I have found that its really not
worth the bother to try to nurse a few more days of bubbles out of a dying batch. Its the same effort just to dump it and mix a fresh one. I use I packet of yeast started in a inch of lukewarm tapwater. I then fill the 2l container up 3/4 full with more tapwater (yes - with the chloramine), dump in a cup of sugar and go. It will run hard for 2 days, less but steady for another 12 or so, then trail off for another week. I refresh every second weekend like clockwork as part of standard tank maintenance. The difference achived with treated water or aquarium water is maybe two days. You're standing in front of the sink anyway, just use the damn tap. Feed the output up into the filter siphon (cannister). The filter itself makes a dead simple and superior reactor.

Good advice.
I stopped messing with yeast and went to pressurized CO2. No fuss, no muss and with a DIY in-line external reactor, I am good to go! :-D Ron |
