I bought a TMC Aquagrow non-return value from aquaessentials. It is now hooked up together with a bubble counter to an UP CO2 "reactor" inline with the return pipe to the tank.
Trouble is, very slowly water is coming back through the non-return value and collecting in a glass jar that the co2 tubing end point is terminating in.
The valve itself is upright (words written on the side are) attached to the side of the tank. Above it is the bubble counter. I thought this was all the right way of doing things?
What might I have done wrong? I can't actually see properly how the device is supposed to work, after all the small red "bit" inside the glass is able to move up and down although it rests at the bottom all the time.
