Thanks, Janet!

I keep in memory the first two years we were in the house, when pool maintenance was so easy, and the ease and pleasure of late afternoons by the crystal clear pool....precious memories.... I intend to give it 2 big bottles of bleach tonight, check the Cl after an hour or so, and then again in the morning before the sun hits the water. At least here near Atlanta we can probably swim til the end of September.

I think I'll try some of the DE equivalent in the filter, 1/2 cup at a time to give a 1 lb pressure rise. What's to lose, only some cellulose fiber....
