Why on earth did they put it on powerpoint instead of a PDF. Well at least I have the TAG issue.

Default CO2 DIY Tarah Nyberg

Hello,

I have a little question for you...

I just got the following, 7 liters pulverisator ready...

I found the Tarah Nyberg recipe for CO2...

I was wondering did anyone tryed to add either gelatine or pectine to the solution... In many site they seems to mention that it makes the whole thing much more stable since not all the sugar is available at once to the yeast... It must slowly break through the gelatine to reach the sugar...

If so I would like to hear about it...

Cheers...

Any how if nobody has heard about it I will try it...

My goal is to reach at least 4 weeks of constant bubbling around 60 / min ... I have a 90 g planted tank my ph is now 7.4 and my gh and kh around 9. That is dead on montreal city water parameters... which makes sense.

Cheers

I've got a PDF of it, but I don't want to post it because I don't have permission to host a copy of it. I can email it to you if you PM me your email.

Default Ammonium Sulfate Alternatives

If yeast benefits from the ammonium in Ammonium Sulfate, would urea work as an alternative? Anyone tried this before in the Nyberg recipe? I use urea as a fertilizer (don't worry, it's for the plants in the garden, not in my planted aquaria) and it is relatively easy to obtain.

Thanks.

I have tried urea in the recipe instead of ammonium sulfate. It works! Lot's more CO2 production... although naturally the mix does not last as long...

I guess you could vary the formula to get the desired amount of CO2 production. Need to experiment a little since the output is dependent on many factors such as ambient temperature, amount of yeast, type of yeast etc.

Default Re: The Nyberg CO2 Method

So, can this method be used with the first set up? I'm confused about leaving the yeast in the container from previous batch. Do I have to add yeast to my initial set up. This is my firt time using the fermentation method. thanks.

Jeremy

How much yeast do you add?

2. Add 1~2tsp of protein drink mix. The author suggested using soy powder as a cheaper alternative, which is what I do, and it works great.

3. *Optional*Add 1T molasses or 1tsp ammonium sulfate(yeast growth benefits from ammonia, hence the use of tank water).

4. 1tsp baking soda to maintain pH stability.

Hi uwintoday

You can use tsp to 1 tsp of yeast in a 2 liter mix. tsp may be a good starting amount and then you can see how it does and adjust as needed.

Basically:
Less yeast = slower CO2 rate, but longer lasting mix.
More yeast = faster CO2 rate, but shorter lasting mix.
