Final update:
Kudos to Pool Doc, Watermom, Chem Geek, and all the others who helped. It has been 1 month since I replaced the water in my pool. Using the BBB Method, my pool has been crystal clear, and guests have all commented on how nice the water is (no chlorine smell, no burning eyes, sparkle, etc.) The method works; this forum is invaluable; and the people here are extremely helpful. Thanks to all. Now, who has any ideas about making summer appear in NW Indiana? It's August and I've had to run the pool heater several times in the last week!
