Local area pool store water testing descrepancies

Thanks all...figured no one size fits all.

Had to drain about 4" of water out of the pool Thursday as we left for Litchfield, SC beaches for the holiday weekend as they were calling for 4-6" of rain in Charlotte. I'm not sure how much we got up there today, but this Tropical Storm down here in Litchfield, SC was a pretty neat experience.

When I get back, I'll have to do some additional testing to se how much the rain impacted my pool chemistry.

On an aside, I think I may have discovered the culprit for my high CC level prior to my shocking last week. I suspected my Polaris 360's float was not working as effective any longer due to it not running optimally. When I checked/unscrewed the float, it was full of green algae water along with a bunch of algae on the threads. I never even gave the cleaner a thought that it could be the source, or at least a contributing factor to my high CC's or near algae breakout.

The easy answer is: Anything in the pool can be a source of algae. You would think, being the chlorinated water it wouldn't, but the problem is that the water isn't moving inside the light hiche, inside the float, inside/behind/under stairs and ladders. This allows the chlorine to get used up and then algae can get a foothold.
