Sorry rubberdoofa, we did run away a bit with it !OMG!!! your well over my head mate lmao, havent a clue what you just said ,
I blame craynerd, for asking all those questions LOL !
It is called Sodastream ! Like you were first asking
Check out my post (Number 10, in the thread)
You were asking if you could use bottles of sodastream fizzy water. All I was doing was describing a method of feeding the sodastream gas directly to a diffusion(dissolving) bell in the tank without first having to put it in a bottle of water.
But it does need a bit of DIY and experimentation, so it may not suit everybody.
