I'm in the process of SLAMing in order to remove what I have perceived to be algae. I began the process yesterday, by adjusting the FC level to 20ppm (based on the shock level recommendations for my CYA level).
I began the process around 3:15pm and checked the FC level approximately once an hour until night set. During that time the FC level remained at 20ppm. The pool was also completely brushed during this time.
Unfortunately, I did not get a reading at dawn, but my 10am reading this morning FC level was 18.5.
All readings have shown an CC level of less than 0.5.
The picture above is what is currently collecting on the line between the shallow and deep end of the pool. The left hand side of the "material" is the slope into the deep end.
What is this stuff? Is it living algae? Is it just dead material that needs to be removed and it collects easily on the top of the slope?
While I'm at it, is there anything I can do to correct the bleeched out look at the edge of the floor and wall on the liner?
