My pool is ozone and i use bleach. I'm convinced the ozone really isn't doing much of anything. When the ozone generator finally goes out, I do not plan to replace it. I've assumed I'll just stick with bleach. The thing I hear about SWG is that it is so corrosive to things around the pool area/back patio. For those of you that say SWG is the only way to go, are you having any corrosion issues? If that concern is overblown, I would seriously consider SWG just for ease of maintenance.
