Using brown sugar in CO2 reactor

Today's just the 3rd day so naturally output will still be high but what I'm really impressed and amazed at is the consistently high output from the mix this time.

I gave up for a few days after some mishaps and decided to switch to pressurised CO2 but haven't decided on a regulator yet and the local shops only stock the Chinese Insta ones so I decided to try yeast and sugar again. I know about citric acid and baking soda but am too lazy to do another bottle and caps since the final aim is for pressurised.

Anyway, to cut the long story short, here's a video and some photos of the silly output from the 2 litre bottle. It's placed in a bucket with some water and covered with a towel to mitigate the mess should another mishap occur.

Bump: The output is consistently high when the valve's fully opened but of course I'm not about to kill my fishes to show or prove that in this video. I know because I've tried it with the airstone in the bucket. There's actually a leak somewhere at the bottle side because I can't get enough pressure to bubble through a ceramic diffuser so that's why I'm using an airstone for the time being.

I use brown sugar and brewers yeast, I'm not going to post how long it runs for as I will just be called a liar.
It also seems to be less temperature sensitive.

Cape Town, South Africa.

Hi. I'm back.

Yeah, I noticed the temperature part too. It's cold today, at least as cold as it can get in the tropics, but the output is still pretty high.

Out of curiosity, how much does a batch cost at your sides? At mine, it's about USD0.50 for the yeast and sugar to fill a 2 liter bottle.

Pressure's built up pretty good to be able to bubble through a ceramic diffuser. Bubble rate is approximately 1bps which I personally feel is very decent considering its source. Was much faster a few hours ago around 0800hrs but I guess that's the 'joy' of yeast and sugar
