Can palm fronds that fall into a swimming pool turn the pool water green?
Yes, and to add to that, the added stress to the filtration system to go beyond it’s ability to remove those contaminants can and will become major problems in the near future. It is incomprehensible to think you would even consider leaving debris in the pool. Left to go out of control in that manner is an unnecessary expense and detrimental to the surface of the pool and equipment.
