This is my second year owning an above ground pool. It holds 24, 000 gallons of water. I am in the process of opening it and just like last year I am dumping huge amounts of chlorine in it and it is still not registering free chlorine when I test the water. This same problem hapened last year and after hundreds of dollars and about a month it finally registered chlorine. Every one keeps saying I am doing something wrong but not telling me how to fix it!

You should also be using a stabilizer with your chlorine. Chlorine in swimming pool water - POOL WIZARD
