These are those spiral types?

Something's not right. You should not have to apply this kind of pressure.

No, the more water flow you add to the reactors I make the better they run
as rule(don't try and add 1000GPH pump to a small reactor etc but within
They have no backpressure in the gas intake. So it take the min amount of
Gas pressure to run.
These were designed with DIY yeast folks in mind so that min pressure can be
used and no water will backflow into the brew or get sucked into the the
tank etc(use a rigid juice bottle etc to prevent that).
A decent CO2 reactor generally will turnover the tank 2-3 x an hour but this
can be less on very large tanks or less densely planted tanks etc.
