Hi everyone, its been a while since I had this brownish looking dust appear on my walls and flat surfaces.Let me start by saying that the water is crystal clear until I brush the pool and the run
the Auqa Bot. The stuff will stay gone for a day and the start to re-appear. Here are my numbers.
FC 8.5 at 530PM Roughly 1 1/2 hours of run time remaining.
CYA 60 I know it probably needs to be bumped up to 70. A month ago it was at 70 but have added water several times due to evaporation and rain.. However FC is still way above target for 60
Wtr temp 84
Cartridge filter was just cleaned less than a week ago.
I had this issue earlier in the year late July and just brushed, vac, ran robot and dosed with bleach and it cleared up until now.
Should i replace my cartridge even though looks ok and is less than 2 years old.
I have inspected inside the light well also. Nothing found there.
