Re: [APD] DIY CO2 in a Red Sea Turbo Bio System?



You surely can. You can even use the very same strain of yeast. All you have to do is, the next time the unit slows down it's output, pour out the contents except for some of the slag at the bottom. Add more sugar and water, baking soda and a bit of protein powder and the live yeast in the slag will multiply and grow quickly -- doubling time for yeast is about 2 hours -- if you do the math, you'll know that over night you'll have a full supply.

If you need a new starter culture, almost any yeast will do although wine yeasts can work better because many of them can tolerate higher levels of alcohol. You can find diff varieties of wine yeast at make-your-own wine stores and web stores like this:

An excellent recipe can be found in Tarah Nyberg's powerpoint presentation from here presentation at the 2003 AGA Convention, which you can find here:

Good luck,

Subject: [APD] DIY CO2 in a Red Sea Turbo Bio System?


Greetings,



I have a silly question. Is there any reason why I can?t just put yeast,
sugar & water into my Red Sea doohickey instead of paying 20 bucks for 3
refills plus shipping? I mean, that?s all it is, right? Just pre-measured
and with pretty packaging?



I?ve looked around at various DIY CO2 instructions, but they seem to be for
set-ups with a significantly larger capacity than this little thing (one
liter? Half a liter? It?s not very big?) I?ve also seen a couple of warnings
about messy accidents with DIY.



So ? what do you think? 



TIA,



Rebecca
