I have an Aquarite SWG and love it for making life easy. Don't forget the side benefits (that most SWG users feel) of the softness and better feel of a salt water pool.

I still use bleach for shocking when I need to (opening plus cases where I screwed up and the SWG "fell way behind" - my timer presets got screwed up and the filter/SWG didn't turn on at night after a heavy use day). The combo works great to balance convience (SWG) against control/quick results (bleach). I prefer the SWG but love the option of bleach when I need it. Best of both worlds.

Controlling PH has not been much of an issue for me. There is a thread about that now, one of the senior forum users is very chemically astute and is trying to figure out why SWG in vinyl doesn't seem to have the PH issues that SWG in gunite does (not sure how fiberglass fares). In fact, I have had to raise my PH slightly (using Borax), not lower it (yet).
