We've had some signifcant rain and the FC level in my 8500 gal. vinyl inground pool in at 2.8. I'd like to raise the level to about 3.5. Can I use regular Clorox to raise it? If so, how much is recommended?

Other question is the pool has a Pentair InteliChlor SWG set at 20%. Instead of the Clorox, should I just increase the % on the SWG to get the Chlorine up?

Thanks

In an 8500 gallon pool, 2.25 cups of 6% bleach will raise your FC by 1 ppm, and certainly is a good way to raise chlorine in your pool--but if you don't have an excessive chlorine demand that needs to be met by shocking, why don't you just let the SWCG take care of it?

I'm curious--what testing method are you using to get your chlorine levels?

I'm using a LaMotte ColorQ Test kit to measure all the pool water levels. I think I will let the SWG take care of it because i don't have a high swimmer load, etc.

For the record, my levels are:
FCl: 2.4 (error in my original post)
TCl: 2.8
pH: 7.5
Alk: 130
CH: 177
CYA: 61
