I hope so, Danepatrik.
No, the powerheads do not have a venturi, Crazie.eddie.
That is exactly what I fear, Steppin 16.
I had decided to introduce the CO2 just at suction of the powerheads and hoped that the impeller would chop up the bubbles and then while passing through the spray bar under pressure and being forced out through the 1mm holes into the sponge wrapping of my spray bar would be sufficient for the CO2 to dissolve, JT.
Then I posted a thread about a reservoir to store the DIY CO2 at night. The greatest negatives to the idea was that all the CO2 would dissolve in the water overnight.
This put me thinking about introducing the CO2 in the UG grid. The suction of the powerheads would keep the pressure there in the negative, water would be raining in from the top of the grid, by the time the CO2 bubbles arrives at the suction point of the powerheads they could have been partly dissolved and the rest would now be subjected to action as originally planned.
If you have a choice, you have a problem, till you elect your choice. No choice, no problem, only consequences, learn to live with them.
