Re: co2 DIY slowing down...when to change bottle?

[Dave M. Picklyk]

:( I think I made a mistake, I added the yeast cold to the mixture. This
wouldn't mean a much slower restart. I should've waited for the yeast to
warm to room temperature before adding.

Darn.

I recommend removing all the liquid, not adding more yeast. The yeast
is not the problem, it's either they run out of sugar or the alcohol
concentration gets too high. I usually pour out the entire mixture,
leaving the nasty film of yeast on the bottom of the bottle. Then
replace with fresh sugar water, mix, and let them recover. I get quite
a few "charges" out of this method.

The alcohol by-product is what inhibits the CO2 production by yeast in
a fixed volume of a DIY bottle.

If you drain out most of the liquid and add new sugar water, the
remaining live yeast will then have a new food supply and the alcohol
will be diluted to a safe level. This allows the yeast to begin the
process over again and generate CO2.

As long as you have a surviving culture, you can reuse the same yeast
for quite some time before it kinda gives up and you have to start
fresh.

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.

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

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.

iirc the problem is that while producing co2 the other output product is
ethanol which starts to poison the yeast.

diminishing returns...

You can't do it indefinitely, but doing a second 'charge' has worked for me.

The alcohol by-product is what inhibits the CO2 production by yeast in
a fixed volume of a DIY bottle.

If you drain out most of the liquid and add new sugar water, the
remaining live yeast will then have a new food supply and the alcohol
will be diluted to a safe level. This allows the yeast to begin the
process over again and generate CO2.

As long as you have a surviving culture, you can reuse the same yeast
for quite some time before it kinda gives up and you have to start
fresh.

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.

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
