Replastered our pool last month. It has been 20 days since we refilled the pool. Over the weekend, I used test strip to test water. All numbers was in right range excepted Chlorine level is almost zero. Yesterday, I notice there were air bubbles on the surface of water. They are like the bubbles float on the water in the bathtub after you take a bath. I only have chlorine and Hydrochloride Acid on hand. Order a Taylor K-2006 online last night.
just used strip to test the water. FCI: 0; ALK: 180; pH; 8.4; CyA: 40
What should I do?
