So last Thursday I finally got around to getting a CO2
tank for the Rex Grigg CO2
regulator I got for Christmas (that's right....1/2 a year a go). I had on and off searched in the area with no luck. Finally my mom who lives about an hour west of me made 5 calls and had a 5lb tank for $90 (filled). Go figure....
So I set up the CO2
tank in place of my 2 2L bottles. I used the existing tubing which goes to a PH in the back right bottom corner of my tank. This PH has an air stone at the intake which breaks up the bubbles before they reach the PH so there is less wear and tear on the PH and its completely silent. This worked very well with the DIY fluctuations, and I expect it to work just as well with my pressurized system.
So here's a couple pics!
old setup with 2 2L bottles (you have no idea how much I hated dealing with these):
5lb tank and regulator (~950psi in the tank and running ~9psi on the regulator):
line running from needle valve to tank:
PH in tank with air line running into base (air stone on end of tubing)
Setup shot showing CO2
tank and 20 planted, and 10 QT below (I have plans to either hide the CO2
tank inside the white cabinet or at least affix it to the wall so it won't be bumped):
Final tank shot (you can see the PH in the bottom right corner, once the plants fill in from my recent trim its almost invisible):
Hope you all enjoy!
