This morning I got up and noticed a patch of yellow algae on the base of one wall. I tested the water and pool chemistry while not ideal seemed ok
enough not to start algae growth. specifically the readings were;
Chlorine - 2.0
PH - 7.5
Total Alkalinity - 60
hardness = 350
stabilizer - 40
water temp - 83
pump running 7 hours daily.
Weather conditions have been hot and rainy lately.
The patch was small, about 8-10 inches in diameter.
Any ideas as to why this algae bloom started?
