Haven't gone to the pool store to get my official results yet. I am waiting to see if my chlorine levels drop off. This is week 2 of no additional chlorine from either granular or chlorinator. Tested water and still bright/dark yellow above the 10ppm from the 5 hth test kit. Water is still brilliantly clear and being used by my family, though it doesn't make me rest easy. When can I expect to see the levels drop off, will it be gradual or right away. Lately where I live, central mass we have been getting hot humid full sun conditions. I wish there is something more concrete that I could do short of draining the pool.
