The only way to get rid of bubbles in tubing is using "fill cannula" and raising the amount to the maximum, then remembering to change back to your usual fill cannula amount.
If you get a lot of bubbles in the reservoir, you can't be removing them from the reservoir when changing sets. Make sure you tap all bubbles to top of reservoir, using the plunger to press them back into the vial. Even when you've got rid of as many bubbles as possible, after removing the reservoir from the blue connector, tap the bottom of reservoir on a flat surface to bring any trapped bubbles to the top. Leave to settle for a few minutes then connect to tubing and use plunger to press remaining bubbles into tubing. Try to remove further bubbles (even champagne ones that we're told we can ignore) by tapping the reservoir again.
By using this method, I have managed to get rid of the troublesome bubbles I used to get. I hope it works for you too.
