Just wanted to get some opinions. This is the second summer with my pool and it really does seem to run itself. The water is clear, no ones eyes are burning and i never have any issue with the quality of the water so i rarely test the water. Being a responsible pool owner, last year i brought a sample in to the local store and they persuaded me to buy over a hundred bucks worth of chemicals they said i needed. I felt the water was fine and it wasn't really necessary. So is it ok that i rarely test the water and what could be the negative results of not testing? Its an in ground concrete. Thanks
