Slam ph question

[mchighin]

I am just starting my first slam. Ph before start was 7.6. I added a little more liquid chlorine than calculation suggested (pool shop said CC was 1.1, calc was about 6litres i did 8). Now ph is 8.5, my auto chem. unit is slowly bring it down by dripping in acid. Question: do I even want to reduce ph? Should I just unplug the acid feed and leave filter on and leave ph where it is? Or should I manually dose required acid to drop ph 7.6?

Welcome to TFP!

pH testing will be inaccurate while your chlorine level is high. I wouldn't adjust it until you are back to normal chlorine levels.

thanks guys. slam was successful. spent some time understanding pool chemistry last few days, particularly following some really poor advice from pool shops.
