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, 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.

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

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

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.

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.
