I am looking at purchasing a CO2 regulator off of the net and theres a fair variety out there. It seems like regulators intended for planted aquarium are double or triple the price of something intended for home brewing or Mig/Tig welding. Is there really that much different?? Also, I saw the following quote on the MASA website and wondered if anyone else knows anything about flowmeters (Ive done a search on this forum but not found out anything)
quote: A flow control valve can in fact replace the CO2 needle valve and bubble counter and is cheaper than the two items combined. This valve not only provides the visual feedback, but also provides a reading on how much CO2 is being injected in a more quantitative form (e.g., cubic centimeters per minute; cc/min). The flow control valve I am using is the url=http://www.dwyer-inst.com/flow/rm.html]Dwyer[/url] RMA-151-SSV Flowmeter, range 5 to 50 cc/min air with stainless steel valve. I find I am using about 20 cc/min of CO2.
Heres an example of a Mig/Tig welding regulator. The specs indicate that the flow control is capable of 0 - 25 L/min. Is this suitable for planted tanks??
If this is not suitable and I should get a dual gauge + needle valve, can anyone tell me where I can get a suitable needle valve and Co2 resistant tubing?? Would a place like ENZED Hydraulics stock something like this??? Comments much appreciated
