I'm at a loss for what to do here.
I've got an in ground fiberglass pool.
A few days ago my water went milky colored for no apparent reason. I had been adding some CYA though. overnight test showed a loss of 1.5 ppm. Began shocking. Water is still murky at this time.
Went out this morning to check on things and noticed my pool surfaces both horizontal and vertical have some type of white powdery residue on them. The powder wipes away and you can see the area that was wiped. When looking at my hand there is a bit of white on it. The substance is almost like baby powder in the water.
I did backwash last night and had to add some new fill water.
What could this be? What to do? Help!
CYA last measured was 45. ran out of drops. waiting for taylor shipment.
