Is there a way to convert it to have a slight venturi effect?
I wondered if I could insert a length of 4mm stainless tube inside the gas inlet, and notch the end that sits inside the main tube to let the gas out?

Think it will need more of a constriction to create the pressure drop (suction) for a venturi to work. The trouble with the constriction is it reduces flow so you get less water though the reactor and less swirl. As
@Hanuman was saying he has come to the conclusion that with his cone top reactor the venturi isn't really needed and he is getting the same performance out of his reactor without the venturi.
Most folk will want to keep good flow also for tank turnover.
I am moving over to Hani's conclusion also that the venturi isn't needed if you have a cone like he has or a decent swirl in the CO
2 reactor. If I remember correct when
@foxfish had his pump and reactor with great swirl the CO
2 in the reactor disappeared within 10-15mins after CO
2 went off which suggests the swirl was working well.

I think if water is being forced along with the CO
2 into the reactor it is creating more CO
2 bubbles in the reactor also.
I was tinkering last nigh and by mistake I fitted the power to the solenoid for the high injection rate (as only using the low injection rate at the moment). Got lucky and 35mins after CO
2 had come on had a 1.5pH drop
. Got lucky and lost no livestock - a few fish was gasping
@Wookii did you get one of the Vidao reactors ?
