Everyone is accounted for and test tube is slightly green. I think the co2 level is about right now with the powerhead venturi going full blast and the air(co2) stone bubbling away.

The fish all have like white or burned looking patches on their heads from where they were gasping for air.

You can buy a pH stabilizer powder. And it will take it to 7.0 right away.

I think I have some, though I think 6.5 may be OK as I've had this pH for a while. I'll bump it up a bit.

I just mixed up another batch of yeast and water. I decided to actually measure the amount of yeast and I added 1 teaspoon with about 4 cups sugar. I think the yeast measurement is the most important.

I had to replace the cap again on the plastic jug because once again it split. The co2 must do bad things to plastic.

I'll report how it's going when the yeast is working.

It's a one gallon Trader Joes Newzealand artesian water jug. I should find something else. It's just that I have these handy. What do you use?

the cheap walmart brand gallon water bottle......i was thinking of doing a 5 gallon water jug, but i think that would be to much....

I don't know if the yeast multiplies after it munches on the sugar. If it doesn't then the amount of yeast used should determine the rate of co2 generation, and the more sugar you use, the longer the co2 should flow. I'm thinking that at a certian point there will be a toxic amount of alcohol which would kill the yeast. When using a smaller container with less water this toxic level will come about faster than if you use a bigger container with more water.

I'm just guessing at all this. What do you think?
