Hello Przemek,
Trying to start the new AC2 version without the reflow valve,
Actually running 1 bubble/sec, the gas chamber get's a lot of bubbles going down until the bottom and going trough the media chamber.
The flow valve inside between the chambers is most fully closed. Then the media chamber start to get a lot of gas on the top and without reflow valve this gas get trapped there.
The degassing function seems not doing anything to this trapped gas on the top.
Can you please advise ? We are stuck to run AC2 since one month now!! After missing EU cable for the controller and 2 defectives solenoid valves, no solution can be found for the Co2 issue.
