Ph / alk question

[shannonck]

Hi! I’ve been doing very well this summer after slamming initially. noticed my ph dropped from 7.4 to 6.8 over the last couple of weeks. Tc was steady at 4. Found some algae growing today on my light after two days of heavy rains. I use pucks but keep liquid on hand to raise when needed. After I scrubbed and vacuumed it got cloudy and tonight’s reading are
Alk-50
Ph-6.8
Tc-1
Cya-40

do I shock with liquid chlorine or do I add baking soda or borax. I’m alittle confused.

Add 20 ppm of TA with baking soda.

Then follow the SLAM Process.

My pool is 24,000 gallons so that’s 3 lbs of baking soda correct?

 

[mknauss]

I get 7 lbs.

Ok, as always, thank you so much!
