1 co2 tank for 2 or more tanks?

[timwag2001]

anyone have a setup divided between multiple tanks? what does it entail?

Mutiple valves are available.
I did a search for "multi tank co2 regulator +aquarium"

and came up with several links like this one
CO2 Needle Valves

If you're only doing 2 tanks, there should be no problem with "T"ing off the regulator. You might want 2 needle valves though.

You should look at this too

I use this, works great. Ran 3 tanks off 1 CO2 setup for a long time.

You can't just use a T to split the flow. One aquarium will end up getting all the CO2 due to differences in water pressure. You have to have a manifold to split the flow and a needle valve for each aquarium to control the flow to each aquarium individually.

and co2 will break down plastic which most t valves are made of.

I stand corrected

That shows to go ya, this site is excellant!

I used some ball valves and a t junction for awhile before buying a dual manifold/needvalve setup. It worked, but it was a PITA. It required constant adjustment (daily) or otherwise (like Purr said), all the co2 would find it's way into 1 of the tanks.

With the brass 2 way manifold installed, I do not have to make any adjustments whatsoever.
