Thank you. This is my first year ever owning a pool, so I apologize for the questions. If the "algae" I am seeing is indeed pollen, would it make the water turn green too? When I brushed the pool the day I found the algae, it brushed off rather easily and created a cloud after the brush stopped. My pool is around some tall crepe myrtles and it often will shed into the pool. My phosphate count was >1000 based on the pool store testing about three weeks ago (before I officially converted to TFP). My water is clear now and it has passed the OCLT last night. One odd thing today is that the FC dropped about 4ppm and no one used the pool at all. It is in the sun from about 10am - 5pm, but I was surprised that it dropped that much. Is that normal?
