I'm dealing with this right now. Second season in this house, and the pool sits underneath a very mature, very productive 70-foot pecan tree that dumps billions of catkins into the water for about 2 weeks. My hobby right now is scooping and skimming about 50% of my day. Just when you get it momentarily clean, a breeze kicks up and another 1000 fall into the pool. After last year I vowed to wait until that damn tree was done dumping before opening the pool, but between the cold spring delaying blooming and my wife wanting the pool open I am right back there again
Once that tree is done and I can get the chemicals stabilized it's not TOO bad. But until then I want to do what my buddy advised -- raise and sell Tilapia in it.
