This is the recipe I used:
2 Cups of Sugar
1/2 teaspoon of yeast
1/4 teaspoon of baking powder
Only way you can know for sure is get a drop checker.

How big is your tank?

It's a 29g.

I'd say as long as you've got good flow in the tank and not too much surface agitation you're probably fine.

You could do a before/after check of the pH to get a rough idea. The more it drops, the more CO2 you have.

that's what I've got my DIY rig in..... I'm getting almost 2 bubbles per second.
it DOES take a good 24 hours for the yeast colonies to get big enough to produce that amount of Co2.
(I'm also using two 2 litre bottles in the same 29 gal tank)
don't rush it... probably the biggest issue I've encountered has been simple impatience

It's been more than 24 hours and it's still the same. Maybe it's the yeast, I used Hodgson Mill active dry yeast.
And I'm only using one 1.89L bottle, I guess I have to add another.

the yeast should be OK.... that stuff either works (and multiplies like mad) or it doesn't do a thing... if it's dead/old...
I'd suggest 2 bottles twice the co2...
you MAY also want to try some Winemakers yeast... alcohol doesn't kill it as quickly as bread yeast... if you have a local supply, great...
otherwise http://www.midwestsupplies.com/red-s...ier-cuvee.html is a good one.

I'm noticing that it's releasing a lot less than it was yesterday. It's still at a "shot" every 3 seconds but with less tiny bubbles.
I made the DIY CO2 two days ago.
Then set it up with this reactor yesterday.
So after about 48 hours the DIY CO2 is producing a lot less CO2, any ideas on what the problem is?

DIY yeast CO2 is like that.

It could last for 2 weeks or it can fizz out in one day.

No need to look for an explanation. Just experiment with different kinds of yeast.

will this be overkill for a 6 gallon tank? Mind you it is a eclipse 6 system, that has a bio wheel, as well as it kind of waterfalls into the area with the filter.

Yeast need nutrient. A tablespoon or two per bottle of yeast extract, vegemite, powdered milk or soybean, egg white, or basically anything readily soluble that contains protein, phosphate, and vitamin c. I heat kill yeast in lemon juice then freeze to make my yeast nutrient.

If you don't give your yeast nutrients beyond sugar, then they won't have the resources to multiply and colonize vigorously. Sometimes, this will result in fermentation starting then fading quickly, a stuck fermentation as they call it in brewing.

Also, I strongly second the recommendation for wine yeast. Nothing beats it for longevity and productivity.
