Hi - Total newbie here! I'm living in a rental house with in IG pool in the backyard.
The pH is low - 6.8. I've added about 9 lbs. of sodium carbonate gradually over the past 36 hours, and the pH hasn't gone up. I can put in more, but I'm wondering if there's something I haven't considered that's keeping the pH level low.
I'm testing with new AquaChek Select strips. The water looks good - clean & clear.
Here are the testing results:
CH: 0 - 100
CYA: less than 30
