pool just got cloudy

[suzook]

Brand new pool. Been open for a month swg in ground vinyl.
Fc is 5
PH 7.8
CH 175
Cya 50

I never backwashed filter...is a de. I just backwashed and added more de. Should I wait overnight and see what happens? Or add bleach to bring chlorine up??? Pool water is 90.

Did the FC ever drop lower? Was there just a lot of use?

Certainly would not hurt anything to raise the FC up some closer to shock level and filter it overnight. You could also Perform the Overnight Chlorine Loss Test to make sure nothing is trying to grow.

Please add your pool details to your signature and as described HERE as it will help us help you in the future.

Not a lot of use. I turned my vs pump on high for the last 3 hours along with a backwash. Pool is almost clear again. I think I'm gonna add an extra hour or two to my high speed.

I would still suggest bumping the FC up towards 20ppm with bleach to help kill off what ever the problem might be and do the OCLT to know if you should SLAM.

I added bleach last night. I'll do a oclt tomorrow night to see what's up. Thanks.
