my setup is pretty much what you are looking into. aerators are common around here, and they suck.. as u have learned. i haven't pushed them for years. personally i wouldn't use bleach, or any other chemicals to keep up with. i'd use one of the filters that injects air. water-right makes one and i've seen the 5 button clack valve used for it too. maybe others i don't know, i'm more of a well driller but i dabble. i've used a few of both the water-rights and the clacks for sulfur or iron with good results. nothing to keep up with and no maintenance. hook it up, set it and forget it. good luck whatever you decide.
if interested heres a water-right brochure on their flavor and kinda how it works. http://www.water-right.com/library/d...IMS_IMB_SS.pdf
