Photos attached. Appears to be grayish to tan in color.
Keeps coming back even when water is balanced
20000 gallon above ground pool cartridge filter - new filter
Cya 59
we had a cya of 110 so we have drained and filled to get it to 59
before we start treating this I was hoping you could help us identify what it is and a course of action
its spread pretty evenly along the pool the whole pool bottom. Collects in center and liner seems most
None on the walls does not feel slimy. Water appears clear
Cant seem to vacume it out even with sock filter. And robot with filter down to 2 microns
Did two algae treatments one when cya was high and one when we got it down.
Now using unstabalized shock and tablets.
