We had our pool installed last summer. It has an automatic chlorinator we have set high in the summer. We shocked once a week too. Problem is, we never could keep a chlorine reading past 2 days. Then would show low or none. We have a large fiberglass pool. I take my water in to be tested and every time they say "everything looks good, you just have no chlorine". There last suggestion was to pour liquid chlorine in. We did a whole jug and it lasted about 3 days. So we put in another gallon and it lasted a week. Its a 13k gallon pool.
Any advice. Keep adding more jugs of liquid chlorine. Even in the summer, after shocking it would only last maybe 2-3 days with getting a reading. Its up to 70 degrees and my kids want to swim next month (hopefully) so we are trying to get the chemicals right!
