Great news on the clear, blue water! That's what we're all shooting for.

As to the Taylor test kit K-2006 I like www.amantoind.com for online shopping. The direct link to the K-2006 and K-2006C is <http://www.amatoind.com/advanced_search_result.php?keywords=k2006&x=0&y=0> ; the 2006C has more reagent than the 2006. I like Amato because they ship very quickly and have refills available in different quantities.

You said the chlorine is still holding this morning. What is the FC and CC level, do you know?

Has the CYA in the tube sock dissolved yet?

My personal approach is 'one thing at a time'. I'd get the CYA project finished before tackling the stains and the iron in the water.
