diy CO2 idea

[ryf]

ok so I am thinkin I might have thought up a good DIY Co2 reactor that won't risk blowing out... its made of PVC, should cost less than 30 dollars, you'd need a diffuser, and thats about it. included is a pic. the ball valve is for regulating flow. you cant take it apart, but you can wash it out pretty good since the two removemable screw down pipe covers. I can't use it myself, my tank is only 30 gallons, and only have 2 bulbs in there, you can increase the depth for more capacity.


obviously this isn't original thinking, someones probably done it, its the same idea as a soda bottle style, without the use of soda bottles (and no blowouts).

more expensive, but gives you more pressure retention
a 0-10 psi regulator up to 150 psi input (way more than needed)

and an adjustable pressure relief valve set at 100 PSI

you would put these where the ball valve is, and it would replace the ball valve (you could tap two holes or use 2 "T" fittings on one hole if you use an PVC glue on adapter/reducer)

these would be the best way IMO, and its still under $50 total (these two add another $20 after shipping I'd estimate)

Not a bad Idea, but if your over $50 for a diy you'd be better of just going all the way to pressurized IMO.

agreed, it can definitely be done in the $20-30 range, the regulator and hi-pressure BOV, are really only for those who are needing maximum CO2, and would be making a bigger depth and diameter rig, those are an extra $15 not including shipping, and probably would only benefit the pickiest of users, the biggest benefit over the bottles, is that these could go 100+ Psi far above what should be needed for this process, a "safer" bottle method
