Poolmath says add 1 gallon and 1 qt chlorine, which I just did. I’ve been brushing the pool daily and just can’t understand why the water isn’t improving. We used Poolmath for the last 2 years and opened a pool that had been closed for 3 years using only this method, so not completely new to the process and have had great success in the past. Any help?
