Default Nutrafin CO2 Natural Plant System?

Anyone have any observations on this type of CO2 product?

I bought one this week actually. While I'm normally a DIY-type guy,
I like to see how someone else does it first. My LFS had it for like
$25 or so. Seemed beneficial to me to pick up.

The actual yeast chamber is pretty nice. It's pretty heavy-duty,
double-ply thermos-like hard plastic. The diffuser is fun to watch
::-).

All in all, my next tank will be done via DIY, but if you're not into
that, seems like a good setup to me.

I found its instructions in PDF format on the web.

(1) It's only rated for 20 gallons. Does it seem like it would be enough
for 30?

(2) It has two separate packets of stuff that have to be replaced monthly

I have been using it for a while now.
I have one on a 75 UK gal tank. A bit of an experiment I guess.
I have noticed better plant growth, and a nice drop in pH as a result.
The two sachets are just yeast and baking powder. Much cheaper to use your
own.
I actually bought another today, and now have two on my tank with 1
diffuser.
They each take 100g of sugar and 400ml of tepid water, about 1/4 to 1/2 tsp
of yeast and some baking soda.

The diffuser is the part that has made it worth the money. Otherwise use a
DIY generator too.

Disclaimer - I'm far from an expert on these things, as I'm running my
first ever planted tank (20 gallons).

The effectiveness of the system would depend on the amount of CO2 gas
you're producing and moving through the diffuser. I'm using just the
Nutrafin diffuser with my own DIY yeast-in-a-bottle, not the whole
black 'tank' assembly. If I wanted to use it for a larger tank, I'd
simply hook up another yeast bottle to the same diffuser.

I'm quite sure the diffuser would serve a 30-gallon tank just fine.
The limit in the complete Nutrafin system is simply the amount of CO2
it can produce. It looks to me like that's about the same limit that
any yeast-based CO2 system would face.

(2) It has two separate packets of stuff that have to be replaced monthly


This is a key reason I went with the DIY for the actual CO2
generating. Yeast, sugar and water are a lot cheaper and more
convenient.

The reaction chamber didn't produce enough CO2 for my heavily-planted 29
gallon tank. I kept the diffuser (good product) but replaced the reactor
with my usual 2 quart juice bottle. YMMV.

Yeast and a "stabilizer" which is probably baking soda meant to keep the pH
of the mixture up. Both can be bought much more cheaply at your local
grocery store.
