RE: [APD] Can one just give up?

You need to reduce the CO2 injection rate.

Not sure how this is done with a DIY setup.  On a pressurized setup one
usually uses a bubble counter and then fine tunes the bubble rate with a
needle valve.  Or a pH controller which turns the CO2 off and on (via a
solenoid) depending on the desired pH that you set.

I would hesitate to use some type of valve on a DIY to reduce the output
because you will put backpressure into the DIY bottle, risking it
breaking/exploding and then yeast will be everywhere...

If you're using more than one bottle of DIY than you could try removing one.
