I am going to have a 24 foot ag pool installed next week and I don't know where to go from there. It is about 15,000 gallons and it will have full sun all day. I am not sure if I should use chlorine pucks or liquid chlorine. When I first get it filled what are the first things that I should do in order to get it ready? What are better test strips or the drop testers? How often should I run the pump? I am getting a lot of different advice on everything. Please help.
