I don't know if it's the sun, the heat or what but my inline rainbow 3" tab chlorinator is turned up all the way (5)
and every two to three days my FC is at 2 or below. I've been supplementing the chlorinator with
a bottle of Bleach (1.42gal 6%) every 2-3 days just to keep the green algae away.
Pool: 30K gal. IG with DE filter running 9hrs a day. current water temp 87 degrees.
I've had the pool sparkling clear last week, but with a heavy holiday swimmer load,
I've got a little cloudiness that should clear in a few days or so.
I'm located in Austin TX so it's been hot, sunny in the mid-90s for most of the past two weeks. I've been adding
about 2 tablets to the chlorinator about every 3-4 days. Should I be seeing this type of chlorine usage?
My one area of concern is my CYA is high. After diluting my last test, I got a number of around 180.
This got me thinking, with a high CYA level, my FC is not as effective, so does this promote algae growth which
in turn consumes the chlorine at a faster rate? I've read that with a high CYA I'd need about 14ppm FC to be
effective. So with my FC around 2-6ppm, am I stuck in a rapid chlorine cycle of not effective chlorine which promotes
algae growth which consumes more chlorine? Does this make sense? The one thing that doesn't support this is the
fact that I've got a fairly clear pool.
As soon as the kid's swim lessons are finished in two weeks, I'll probably
drain the pool and get my CYA under control. Yes I know the 3" tabs add CYA which in turn will lead me to drain/refill
as opposed to using BBB.
I'd like to get to the point where I can use the inline chlorinator set on low and supplement with Bleach so that my CYA
doesn't creep up as fast. I'll admit, having a bucket of 3" tabs is a lot more convenient than reminding my wife to pick
up bleach at the grocery store weekly. Let alone the storage requirements of bleach bottles.
So does my high CYA and high chlorine demand theory hold any water?
Thanks for your help,
