I have one of the liquid-drop type kits that tests for chlorine, pH alkalinity and acid demand. I tested Monday night and got:
7.6 pH
140 PPM alkalinity
I tested last night and got:
7.6 pH
130 PPM alkalinity
I took a sample to the pool store today and got
8.0 pH
53 alkalinity
Chlorine being low I understand. I need stabilizer and I am fighting some algae.
Now it rained overnight so that could explain why the pH drifted up, but alkalinity is way off. I realize the test is subjective regarding color changes but that is a huge difference. Could the rain make that much of a difference?
