I encourage you to switch and wish you the best. It will work! An alternative method I used last year is as follows: Starting with a relatively algae-free pool, I stopped Baq additions about Aug. 15. Letting the Baq gradually decompose to zero level, we also stopped using the pool (no kids and my wife and I were OK with this). I added sodium monopersulfate oxidizer frequently (about 3-4 lb./week. in a 20,000 gal pool) until closing around Labor Day. When I opened in the Spring, my Baq reading was zero. I started the bleach additions per Pool School instructions and got no color change or muck. It did take about 2-3 days to pass the overnight chlorine loss test, but I used relatively little bleach (maybe 8-10 gallons of 6%) and was swimming in no time. I plan to use this method on my son's AGP this Fall. Downside is you don't swim from now until closing (persulfate is an oxidizer and is not approved as a sanitizer). On the other hand, if you live in NJ or north you only have about 2-3 weeks left anyway and the conversion will take the better part of that.
