1 pump, 2 airstones?

[Divinityinlove]

Can anyone explain why when I connect two air stones to this 1 tube, air only ever comes out of 1/side/ stone? Guessing it is physics.

I tried with multiple connectors, two tubes and 3 air stones, switching them around. Is there any way to make it happen?

I’d guess that the density of the stones are different , try taking them both off and see if the air is 50/50 or wether one line is still pumping more air

Obvious question but is there something stuck in the splitter? Have you tried flipping that around?

You have to run separate lines with double valves.

Not sure what you mean?

Nope I checked under the tap and I also tried two from the box. Checked both under tap.

something like this

Yeah, it's just physics. If one stone is even slightly less dense/more porous than the other, all the air will go that way. If you want to run multiple stones, you usually will have to put them on a valve like BrianK shows above. Then you can adjust the air pressure to compensate for the different properties of the stones.

Thank you - I'll check for them
