Hi,

Sorry for the confusion on the FC. 2 days ago I shocked it to 27ppm. Today it was 21.5ppm. Tonight I shocked to 37ppm. So, it hasn't been less than 20ppm for a couple days.
I test with the TF-100 and Taylor K-1000.

I scrubbed the algae with a brush on a long pole and there was no change. No dust or anything. No change at all. It remained as it was. Is it pollen then?

How would I get rid of pollen if it is that?

The algae or pollen is at the bottom of the deep end on the floor, none on the walls. None in the shallow end or anywhere else(it's a true-L shape pool). The pool is full sun(no trees at all) and been open for about 2 weeks. The rest of the pool looks fine and has no algae or pollen.

Yes, I used trichlor pucks for the first 8 years and have been using BBB starting mid-last year. I will drain alot of the water as the season progresses since the CYA is so high.

Thanks!
