Well heck... what I meant to say below was that I guess I will adjust the
CO2 bubble rate until the Ph crossed with the KH give me around 20 ppm CO2
saturation... My KH is 4~5 dH so for 20 ppm CO2, I should adjust the bubble
rate until my Ph reads 7.

DJay - been lurking for so long that I'm correcting myself!

Purchased a 5 lb tank, regulator, needle valve all from sources from
various
posts here and what was available locally. I made a DIY bubble counter
and
after assembly everything is working beautifully and there are no
detectable
leaks! Checked each connection with soapy water and fixed the original
bubble counter which was leaking nearly all the CO2.

Now I have about 55 CO2 bubbles/min bubbling into a reactor inside the
tank.
The regularity and quantity of CO2 entering the reactor is quite a
remarkable improvement over DIY yeast.

Question... I am guessing that I will just measure my Ph to determine the
optimal bubble rate?

Thanks for all the help!

Original post...


I'm tired of doing the DIY Yeast CO2 constantly. I found a local place
that
sells and refills CO2 containers at a reasonable price. Do any of you
have
a regulator that you would recommend? While cheaper isn't always better,
I'm looking for a good value and good quality.

TIA,
