K-2006 came in today. Immediately went out to try out the FAS-DPD test. Showing FC=35, CC=0. Still have what looks like a brown algae accumulating in the wrinkles on the bottom of the pool. Not sure what that is at this point. Will be letting the chl ramp itself back down to 10, while keeping an eye open for any growth of the brown fuzzy stuff.

Here's a picture of what I've been trying to eliminate:



This stuff disappears as soon as it's disturbed, but with careful use of the vacuum hose without the head and connected directly to the filter inlet, it is filtered out. Problem is, it seems to regrow overnight, to about this same level.

I'll get a full set of readings posted tonight.
