Ok guys, need some recommendations for a water softener. Our water hardness is about 15-20ppm. We have Lowes and Menards locally. I checked at Menards and all they carry in the store are Waterboss (poor reviews on amazon) and Morton system saver. At Lowes the 30k grain Whirlpool model has very good reviews. I'm not really sure how large of one i need. We have 1 bath and only 2 people living here. I'd like to not spend much, but i realize this could get expensive... Can we try to stay under $600 though?
