It is because the cynuric acid is very low or zero. Put cynuric acid on your pool at least 10mg/L. Check the cyniric level before adding. Note : high cynuric acid will make the water cloudy. Low to Zero cynuric acid you will loss chlorine very very fast let us say wihtin one day. To elevate cynuric acid in your pool, you add cynuric acid. To lower the cynuric acid delution of water. I will give you the formula on how much cynuric acid you will add after you can give me the reading and the size of your pool including the depth. Can you e-mail me the reading of your parameters. Can you give me chlorine, Ph, calcium hardness, cynuric acid and alkalanity. Thanks

Before using the pool I would sudgest for shock treatment to kill all unwanted micro organism. The normal chlorine would be 1-2 ppm, to do the superchloronation you will rise it to 12 ppm for 2 days no swimming and then, check the chlorine level, if ok, then you can used the pool.
