11,000 VL inground pool-

CYA 40

and once my FC reaches its proper level how much bleach to keep it where it needs to be-

thanks-

In your pool, 3 cups of 6% will raise your FC by 1 ppm. Don't have time or brain cells to calculate it right now, but 1.42 gallons should raise it by roughly 6 ppm. Your shock level with a CYA of 40 is 15 ppm, and afterward you should maintain between 3 and 6 ppm.

You can do this--it's not very hard! And it's a LOT cheaper than the pool store route!!

Happy swimming...........

My CYA is hanging at 40 and im maintaining between a 3-6 on FC...... my PH has climbed a bit to 8.

pool is looking good.

A lot of pools have their "own" pH that they like to stabilize at--mine likes to stay around 7.8 if I don't fight it--and my kids say that the 7.8 is easier on their eyes than the lower pH anyway. Keep in mind, though, that if you start fighting algae again that the lower pH helps the chlorine be more effective, although you never want to get it lower than 7.0, and I would definitely stay above 7.2.
