Any ideas on how to get the free chlorine regent without waiting for shipping? I tried three pool stores nearby and they don’t carry the Taylor regents. They only have the stupid tests that go up to 5 or 8 and the pool store tests only goes to 15! Anywhere else I should try? I started to slam for light algae and then realized I am out of the regent from the test kit. I know I got the pool to shock level but now I am out. Shipping will get it to me around 7/8..
