Default CO2 bubbles collecting in Nutrafin diffuser

If one wanted to get a better idea as to the contents of the stabilizer,
couldn't you measure out the same amounts of it and of baking soda and put
them in two identical sized containers of water that have been tested for KH
before, then check the KH after adding? At least then you might have a
better idea wouldn't you?

probaly since it can be used as a pretty good buffer. That's just
speculation though and I haven't seen anybody being positive on whatever

is
in that packet.

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?

Incredible that they get away selling that stuff at that price.

Anyway, as I said earlier, I wanna keep the diffuser and build a DIY CO2
system for the rest. With CO2 check valves (if I can find those around
here, no luck yet), 2 yeast generator bottle, a gas separator and silicone
or better tubing.

BTW, anybody tried to use non-refined brown sugar like cane sugar in the mix
instead of what the instructions says: "Add white table sugar (no other
substitute)"?

simple baking soda,
I have the system as well but it was so hard to find refill packages of

the
powder I went to just the old yeast and sugar with a little baking soda to
regualte the reaction, just mix it as the instructions said with their mix

and
your off

Of course, someone could just taste it and see.

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

Just as a matter of interest, what did you do during your college years...?

I don't really remember college, but I researched every single one of those
chemicals before I tried them. :-)

My diffuser had a cracked rung, so make sure your's isn't similar.
Hagen replaced mine for free.

Also make sure your unwanted snail population isn't causing the bubble
to jam.

And also make sure that the blue-green algea accumulated on the rungs
is kept in order. If it gets too plentiful it'll make the bubbles
stick...
