Just wanted to post for those that are not
Aware of peroxide bring down the clorine levels.
I saw in another post someone mentioning that peroxide will bring down fc
So I gave it a wirl since my clorine was off the charts from the auto chlorinator.
For my pool a 32oz bottle of 3% peroxide will bring down the fc about 1 full point (ppm)
So I went to cvs and purchased 6 16oz bottles and dumped 5 in, within about 2'hours my fc is down to 3
It was off the chart so needed to bring it down quick cause company was coming to swim
Just wanted to post that it seems to work well and don't
See any negative side affects
