The Problem: Leaves floating on the surface of the pool will clog your skimmers. The tannins in the leaves turn your skimmer basket and piping brown. And then, when you clean out the skimmer, stray leaves get sucked down the pipe. The Solution: I use this handy net for about eight weeks in the fall to keep the leaves out of the skimmer mouth. After a short time they sink, where I can get them easily with a big net.
