I have a 24' above ground pool.
Latest stats are:

FC 4, CC 0 , TC 4, PH 7.5, ALK 100, CAL 110, CYA 30 temp is about 74
I added a liquid solar blanket about a week ago (I think all this did was make the water a little cloudy)

The past 3 mornings, I've noticed, in the middle of the pool on the bottom small green "balls" of something any where from 1/4 inch to 1/2 in diameter.
I can get them out with the skimmer, they don't break up. But, once in the net I can break them up with my fingers. Pool cleaner also gets rid of it.
There is nothing floating in the pool or around the edges, so I'm not sure what this is. I shocked this morning up to 15ppm, so I will see if this helps.
Is this some type of algae? I haven't had to deal with any algae since I got rid of Baquacil. The algae that I had with Baqua floated on the top and the bottom of the pool.

Any ideas?
