Every morning i wake up and check my pool and at the bottom of the pool there is always this black stuff, not sure if it's just dirt or dead algae, i just currently tested my pool water and this is what i got
PH- between 8.4-9 (which i know is high)
So what is this stuff at the bottom of my pool? also when i vacuum it up with my pool blaster max all this dusty powder comes from it and makes the pool cloudy
and this is what my pool water looks like after i vacuum, pictures dont do justice but it's cloudy...
