red dawg Posted August 26, 2009 Report Share Posted August 26, 2009 Have been using CO2 in my tanks for years. I am tired of refilling the 2 litre bottle monthly. Can anyone point me in the direction of a system that is reasonably priced and where i dont have to worry about it for 2 or more months.

werner Posted August 27, 2009 Report Share Posted August 27, 2009 Well, I'm not sure if you'd say that pressurized CO2 is "reasonably priced". But then you have to weigh the $$ against the PITA factor of the DIY. The Milwaukee regulator, etc. is about the cheapest out there, but some people find that they have problems holding a consistent bubble rate. There are other brands out there too, but more expensive. You will have to find a cylinder separately. Price depends on what size you want. Larger ones are a better value (refills too), but if you have to hide it under a tank, the you're probably stuck with about a 5lb. Used tanks are cheaper, but you may have to get them re-certified. Welding gas suppliers (Praxair, Air Liquide) should be able to sell or rent cylinders. I got a used 5lb from Sprouse Fire and Safety, which is where I get my refills- I think it was about $80 (newly re-certified and filled).

Thank you Werner, Besides the pet retailers can I pick this up Praxair or Air Liquide? Quote Link to comment Share on other sites More sharing options...
werner Posted August 27, 2009 Report Share Posted August 27, 2009 You could get a regulator from the gas places, but you would still need a needle valve to fine tune the CO2 down to where you can count the bubbles per second. AFAIK, only the pet places carry something like this. Here's a Pressurized CO2 Primer. Quote Link to comment Share on other sites More sharing options...
