High PH, no CL, about to slam

[jbailey895]

I am in So Cal and late to start my SLAM. Water is around 60 degrees. No visible algae.

0 FC
8+ PH
375 CH
140 TA
0 CYA

I am going to add about a gallon of Muriatic to address the PH first, then raise the CYA to about 40 ppm, then start the SLAM.

Is this the correct order? I typically have high PH and calcium out of the tap here in CA; the rains have been heavy so I'm a bit surprised my PH is so high.

thanks for any suggestions, here's to spring coming !!

Why are you planning a SLAM if there is no algae?

hmm, good question. I always thought it was proper to SLAM at opening to make sure I have a good baseline for the season.

Your choice. SLAM Process and
Overnight Chlorine Loss Test later, or
OCLT and possibly not need to SLAM

With zero fc it’s good insurance to slam.
Since you have no cya do this 1st before adding cya to be sure you don’t have ammonia, with the high ph it’s unlikely but better safe than sorry & it’s a quick check
