Pressurized Co2 Split So It Feeds Into Two Tanks...

[BLASK]

So im thinking of making my non-planted into a planted. I was thinking of just placting a T-tube in the co2 tubing and just making the co2 go into two tanks. I remember reading a thread about this. What are the ups and downs. Thanks

Only thing that I could think of that will go wrong is that one tank gets too much c02. This could be easily solved by adding a gang valve to control the amount of c02 geting into each that. Just make sure you don't put too much pressure onto the gang valves or they will probably explode.

Don't use an airline t-piece. I tried this to split the supply to 2 diffusers in my tank but the co2 seems to pass straight through the plastic.

It can be done but you need a manifold and a seperate needle valve which is normally attached to the manifold, i think Aquabotanic sell them (sorry no link) in auctual fact you can run multiple tanks from the same co2 cylinder by using a manifold with each tank having a seperate needle valve to regulate the flow.

Useing plastic T pieces etc will not do as you have no way to control the amount of co2 entering each tank for this you need a needle valve.

im bumping this because I still can't find a 'manifold' to do this.

zig or anyone else that knows what place sells the item I need let me know thanks.

I can see a problem. ONLY IF the outlets of the co2 injectors are exactly the same distance underwater, and hence have the same backfill pressure, then toy will get an even steady flow into both. Take it to extremes , eg, one under 1in water, the other under 1ft, the co2 will take path of lest resistance and exit from the tube nearer surface.

Applies more to DIY CO2 but the principal will be exactly the same for pressurised kits.

This can easily be done as described in my origional post........... this is why needle valves are used to control the flow to each tank, you can have the diffuser anywhere you want in the different tanks when its set up.

A simple google search throws up dozens of links for co2 manifolds and first on the list is my origional suggestion in my origional post, shop around though, i know this can be done a lot cheaper than what they offer, im no expert on this as i have never done it but i know many have, so there should be ample amounts of information out there if you have a look around.
