One of my pools have a large oak and I mean large. You can't keep the pool clean for five minutes. It has what to drop all summer long. Has a major pollen season then some other junk foliage before the leaves then the big leaves catch the wind and those drop by again and again, when the acorns start it just won't quit. I call that pool acorn soup. They need to get rid of it because you can't enjoy a pool like this.
I did contact them and just waiting for them to get back with me, the horrid white ring was next on my list along with the broken light but the guy that did my drain is going to give me a quote foe the light part so we will see someday
