DIY Co2 Reactor--Test Phase

You know, its about 3/4" wide, transparent, and has fiberglass threads running lengthwise through it. Nothing will tear through those threads.

Thanks, will look into that.

Well, no issues with back pressure in V2., since the gas chamber/overflow leaked like a sieve. So, used the tube inside that chamber to bypass it completely for the time being. Also, removed the Penn Plax splitter in favor of just a T connector. This was due to the possibility of "it" also leaking like a sieve. So, after an entire day of lost production, the system is back on line, got a thicker stream of Co2 entering tank, than V1 could ever have hoped to produce.

Actually when the pressure built up to critical mass, it freaked me out by rushing enough into the tank to make me think someone squeezed one of the bottles really hard. Was a sight to behold.

Yes, my does that the first day or so. I discovered that refrigerated yeast works better than activated dry. I also use a small plastic (clear; provides about 12 in-squared) box held at the top of the tank to catch the excess CO2 from my diffuser and allows more CO2 to getting the water. Works very well - my pH dropped 0.2 compared to not having the box.
