Hello, about 3 weeks ago I set up my pool. It is an Intex 20'x48" vinyl pool. I am having trouble balancing my chemicals and knowing exactly how to run my pump. I am going to post my pictures from the strips I used. I am going to buy a test kit as soon as I can. From the test strips it looks like my chlorine is non existent and ph is high. I took my water to a pool store and all my numbers were way off. Any help is greatly appreciated.
