Aeration of home well water helps the "good" bacteria decrease organic matter and also reduce other  impurities in water. One place you can aerate is the holding tank right after the well pump motor. You can get a fish tank aerator, and tubing, and rebuild kits, for around $30 . (E.g., at marinedepot.com , Hagen Maxima with durable diaphragm .) You may need a rebuild kit every six months.(Your tank will be larger than what the pump is rated for, but remember we are not trying to keep fish alive, and the pump only uses around 6 watts. )

 Install the pump above tank level, feed tube/s through top of tank and wrap the air tubes around something that will takes the tubes to the bottom of the tank. (Porous rock diffusers may clog due to minerals in well water.) Verify there are no kinks anywhere in tubes for free air flow. Do not puncture tank below water level

 Aeration, disinfect ion,  of well, may also be considered. Please search the net for that info.
