So yesterday my numbers where
FC -.6
PH - 7.6
CYA - 50
Alk- 100
Used pool calculator and added 3 (128 oz jugs) gallons of chlorine to start SLAM process, pump has run all night and just tested water and numbers are
FC - 2.0
PH - 7.2
CYA - 50
Alk- 110
This damn pool is going to be the life of me.
I have a 17 ft, above ground pool with sand filter. I’ve back washed twice a day. Thanks
Guys need help!

Re: Guys need help!
What are you saying?
Did you expect the FC to be higher?
Why are you slamming?
SLAM stands for shock level and maintain. With a CYA of 50 you need a shock level of 20 Chlorine / CYA Chart
You need sufficient chlorine to raise to 20 and keep it there, testing frequently not waiting overnight

Sorry guess I should have elaborated, was on vacation for 5 days and in law didn’t add weekly chlorine. Had a little algae bloom. Was trying to shock to get levels up for SLAM process however I wasn’t sure why levels didnt raise to the 20PPM that the pool calculator advised me to go up to

Re: Guys need help!
Depends on the strength of the chlorine, how much chlorine gets used up killing the algae but as Dennis said you just need to add more chlorine.
