Re: Needle valves in CO2 systems poll
> 1)Describe your CO2 setup.
I have two identical systems: 10 lb tank, a single stage, dual gauge
regulator, needle valve, Aqualine Buschke soleniod valve, Pinpoint Ph
controller, silicone tubing w/ CO2 runs into the canister filter
intake. The filter "burps" a couple of times an hour.
> 2)What valve do you use (company name, part number, etc.)?
Some gas flow valves I found in a surplus pile given to our lab. I don't
even see a name on them. With an active pH control, the regulator and
needle valve are relatively unimportant, IMHO.
> 3)How long have you been using this type of setup?
2 years for 1 tank, and 1-1/2 yrs for the second
> 4)Have you experienced any problems with this setup?
None. The controller keeps the pH at 6.9 +,- 0.05.
> 5)If you could change something(s) about your current setup, what
would > it be?
Nothing. Seems to work great. Expense is the only drawback.
> 6)What cV flow rates do you use?
I've never measured it. Maybe 2-3 bubbles per second?
