Balancing (Pool water looks dull)

[mkolb]

Opened pool yesterday. Tested chemicals several times today and yesterday.

FC: 13.5
CC: 0
PH: 7.6
CYA: 30
CH: 210
TA: 100

No debris left in pool, just water look dull.. should I try to lower TA a little? Could that cause the dullness?

Pool water that looks dull is normally due to high pH. Your pH is not high.

Did you test ph with a FC of 13? Wait until it drops below 10 to test for ph.

 

[mknauss]

Let your FC come down to 10 ppm or less so you can accurately test pH.

I tested PH before I raised FC.

Did you lower the pH to 7.2 as per the SLAM Process?

Guess I missed that part. Should I throw some acid in there now to lower to 7.2?

You’re close to 10. Let FC come down to 10, adjust pH to 7.2, go back into SLAM.

Thanks! Lowered to 7.2 and then added some chlorine to bring it back to 12 PPM. It’s pretty close, probably one more day of SLAM.
