Default CO2 bubbles collecting in Nutrafin diffuser

The stabilizer is baking soda

Hello

I notice that instead of going all the way up CO2 bubbles are collecting

in my
new Hagen Nutrafin diffuser forming larger bubbles that just sit there

all the
time. I tried forcing them out of there but eventually they reappear.

Meanwhile,
I saw a working setup in my LFS and it didn't have any bubbles stuck in

it. I
also read somewhere on Google that this is normal for freshly installed
diffusers and eventually this issue will go away. Did anyone experience

this
problem with their Nutrafin diffusers? Will the diffuser eventually

clear up?
And if it will, what's the physics of this process? I.e. what exactly is

going
to change so that the diffuser will no longer trap and hold CO2 bubbles?


I've got one of these two. I think it's great, and I'm totally
satisfied with it. As other have noted, the bubbles will begin to
travel properly on their own after a while.

My question is this: What is the stabilizer? I know that the
activator is yeast, and I suspect that the stabilizer works by somehow
regulating the pH in the yeast/sugar/water mix, but even if I am right
about that I don't know what it is. If I knew what it was, I could
probably buy it much cheaper in bulk, since a three-pack of activator
and stabilizer is about $8! I know the yeast should cost next to
nothing.

Anyone know what the stabilizer is, or want to take an educated guess?
