Created a self made CO2 injection system for this planted tank.
Each 2 liter bottle has a check valve, both go into a T that runs into the 20oz bottle for an air/gunk seperator then one line runs from the 20oz bottle into the tank to an airstone. There is a check valve between the 20oz bottle and the airstone.
Total cost: approx $15
Proof that it works: Priceless
I'm getting a LOT of air coming through the stone and into the tank. I picked up the finest airstone that they had @ the pet store.
The reason I ran two 2 liter bottles is because my first design was one 1 gallon milk jug and I didn't know if i had enough pressure to overcome the water that was sitting in my lines. After setting up the two 2 liter bottles with my new setup I realize I have more than enough.
Original design called for.
Milk jug with check valve leading into 20oz bottle, then going into the tank. There wasn't the series of extra valves to prevent water from coming into the 20oz bottle. I think that was my flaw. I will need to monitor the CO2 levels now because of this increase... don't want my fish to die and I can't put them in the other tank since that would blow my bioload way up there.
I will attempt to distill the mash that I'm creating when it's done fermenting. I'll do that for every batch. I'll keep distilling till it's near moonshine. I should have approx 10oz of some nice hard stuff. (I can heat water up to approx 180* and boil off only the alcohol and use some of my extra tubing to make it go through a cooling tank then down into a glass.) *Yes I'm a nerd and I love to experiment*... next time I buy yeast I'll get brewers yeast but this time I did Bakers yeast since it produces more CO2 but less alcohol.
