This would be pointless. That buildup of air is the CO2, that's what you want to give to your plants (above soil, not to the roots). If you remove it, you have water with a much of minerals in it (if using mineral water). If using water with CO2 added (whether store-bought or homemade), well you just went back to plain water and wasted your time & money.
Not making fun of you or giving you a hard time - just trying to keep you from wasting your time & money.
