I did get the K2006 through your Amazon link.

So, to reduce the alkalinty I should use the method on your site with 'slow' aeration from uncovered pool?

The new sand does seem to be slowly clearing things...hopefully if I get the Alkalinity down things will improve. I'm hoping not to have to use the floc again since I seem to be a very bad vacuumer - stirred everything back up.

Using the best guess chart I see I should keep the chlorine about 10. That's where it was this morning after adding 4.5 gallons of bleach last night. I doubt I got it up to the 25 shock level yet. That's a lot of bleach One gallon raises about 2ppm in 30,000 gallon pool? I know I saw the number somewhere, but can't remember now.

Thanks for your help.
