I just got a small 12' pool and it has been filled for a month and water is not turning green. Haven't put any chemicals in it yet. It is in a naturally shaded area. Put pool shock in it once just because it was a little cloudy. I am supposed to bring a water sample to the pool store to determine chemical balance. But if it stays clear and algae free. Do I need to worry about chemicals? I run the pump for 5 hours at night. TIA
