CO2 for multiple tanks

[chris_todd]

For those of you running CO2 on multiple aquaria, how do you do it? Do you have one tank with a single regulator and multiple manifolds (like these: http://www.greenleafaquariums.com/co2-m ... tters.html), or do you have multiple CO2 tanks, one for each aquarium?

For tanks in the same room, I use a manifold, this one in fact:

For other tanks, their need their own tank+regulator.

There are countless other configurations, however, which are probably on this forum if you search. But, the above are what I use.

Chris,
If you are looking for a lower cost alternative, I used a "mini manifold" to split the co2 output.

Another option is Sean's suggestion:

I buy 'T's used for car vacuum systems for my splitters. I get them at PEP boys. A 'T' and three hose clamps and you are all set. Buy the extra thick walled CO2 line from a home brew supply store for distance runs. Of course you have to remember when I do this I put the needle valve at the tank.

I use Fabco needle valves at each tank to fine tune the flow. I also found that bubble counters were unnecessary for my configuration because I can see the bubbles going into the diffuser and filter intake.

I run two tanks - my 180g is on its own regulator.

Other three aquariums are on one tank, mini manifold and bubble counter/inline needle valve at the end of each line. I did that to be able to see output at the tanks, as my basement is plumbed with CO2 lines and some of the line runs are a tad longer than what most would be doing.
