If your water is blue and cloudy, not green and cloudy, then it's probably NOT algae. Does the cloud seem kinda white to you?

I really think we need to see your Calcium Hardness and Total Alkalinity levels.

What you can do is get the HTH 6-Way drop kit from WalMart Watermom mentioned and test those two things as well. BTW, the Bromine "Test" is the same as the Chlorine test. You just read it differently if you use Bromine instead of Chlorine to sanitize your pool. Otherwise ignore the bromine markings.

The test for CH and T/A in the HTH kit is basically the same as in the K-2006.

You see, I suspect you have very, very hard water and it's precipitated out.
