Godiva,

I would recommend you shock the pool with bleach...not your chlorine generator. .5 gallons of Clorox will bring your Cl up to around 12ppm and should get rid of the chloramines.....the SWG will take too long.

If you'll put in 1 lb of stabilizer, (CYA), your chlorine will last longer and your SWG will not work nearly as hard....extending it's life.
