This is what I use for my DIY Yeast CO2 setup for a 1 gallon bottle.
- 4 cups sugar
- 1/4 tsp yeast (fast acting)
- 2-4 tbls bread flower (or any other flower)
- fill water to about 2 inched from top.
It has been going strong now for about 2 weeks and I get about 8 ppm on a 55 gallon. It is not that much, but I am planning on a pressurized system soon anyway.
Tank in transition! 55 gallons, hard water.
