As I posted before, you should have SOME CYA in the water, even if it's a low 20 or 30 ppm amount. Not having any CYA at all in a chlorine pool is bad on several counts. Not only will the chlorine break down in sunlight quickly, but it will be too strong unless you keep the level very, very low and that is pretty much impossible to do without automated dosing equipment and even then it's hard to maintain anything lower than 0.5 ppm FC reliably. So again, please add at least a small amount of CYA to the water.
