Just started with this pool thing. Have an above ground 12x24 inflatable pool Ordered the pool testing kit but will take a week to arrive in Canada. Have had pool going for 3 weeks. Tested with red and yellow kit from local home store. Pool stores are 60 miles away. Has never shown any chlorine and pH is always off the chart high. Have shocked 2 times. Have used muriatic acid twice-about a cup each time. Have had a puck floating around all the time. And trying to run filter a lot. But all to no avail. The algae is growing as I type!! Please help. What can I do since I can't test the pool for another week. I fear I'll have a swamp by then!
