One Co2 Tank To Two Tanks?

[Phage]

How can I make this happen? I tried to use something that looks T shaped and screws down the tubing like regulators do to the line.
But I couldn't get the co2 to go to both tanks. It would go to the smaller, farthest fishtank. No co2 would go to my bigger tank. The smaller one uses a bubble ladder and the bigger has a diffuser.
Thanks.

Its a pressure problem... a ladder offers little resistance to gas flow, a diffuser NEEDS relatively high pressure.
That said, as long as theres enough pressure to drive the diffuser (which suggest bottled gas ?) then you should be able to reduce the pressure to the ladder.
I would be trying to to "T" off near the supply, and run 2 needle valves to reduce flow.
So, I cannot see why not

Ah ok, so I should buy a diffuser for the smaller tank then and get 2 needle valves?
Thank you.

I take it this is a 90 degree T section? I would expect your putting to much resistance on the line leading to a back flow which adds to the turbulence and increase the pressure. I would use a Y connector as it causes a lot less turbulence along the line. I would also add a gauge to each line so you can check there is equal pressure even if you only buy or borrow one and swap it around between the lines its always good to test them. I think the fitting your talking about is a compression fitting

"turbulence" ?

you could buy one of these:

Well there was some sort of "turbulance", I noticed the pressure gauge was moving up and down So I just put it back the way it was.

Wow those are expensive, lol. But thanks you guys.

Yes if you are pushing any substance against a flat surface it will deflect and a portion of that defelection will be at 180 degrees. Not to metnion the width of the pipe inlet adds another element to the range of deflection and possibility of going back up the inlet pipe. If you use a Y splitter then the surface area available for deflection is greatly minimised providing much better pressure and airflow.

Really dumb question.. how would I attach it to my regulator?

I have this one:

it screws in just after the solenoid.

This is low pressure, REALLY low flow gas... I reckon you are "over thinking" this a tad !
