:welcome: There is alot of very good information here

Fish? I only talk plants.

If you want to chat, come check out the next Calgary Aquarium Society meeting (there's a big auction coming up too.) I'm the chick with the library books.

Sorry already going to a water symposium that night. Will try for October!!

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.

Thank You, Werner!! See that you also live in Calgary if you so desire maybe we can meet up and talk fish?

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?

:thumbs: I think that this is a great site. I have two freshwater tanks and just inherited a hermit crab. Any help with the crab would be great.

Thank you to everyone who welcomed me. Remember "when you get to the end of your life, make sure it is your life you've been living and not someone else's" :smokey:

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.

We do a w/c of 25% once a week. Have been doing this for 25 plus years. Never have a problem with new fish dying or my old ones.
