Hello group. I opened our pool to a good amt of "dirt" on the bottom. I cleaned as usual with a robot and got the pool balanced. New sandlike dust on the bottom everyday. I thought my robot kept missing certain areas. Other than that the pool is clear and looks great. I thought pollen, yellow algae... I put a skimmer sock on the basket and collected this gunk. I brushed the pool several times and run the pump on low all day long. I used yellow gone and shocked it and replaced the sock. It looked better the 2nd time so I replaced the sock again hoping for white but now I have this again. I also float a tennis ball in the skimmer and it now has this black ring on it today. I cleaned the cartridge filter twice, the first time it had grime the same as on the sock. Raining today so I haven't been able to get a look at the filter again. any suggestions?
The pool was super chlorinated when I tested so I knew chlorine would be high:
FC 7.97
TC 7.97
CC 0
ph 7.7
Alk 143
Hardness 156
cya 51
iron 0
copper .10
phosphate 742
I haven't hooked up the heater yet until I figure out what this gunk is so the water is pretty cold.
