Amazing as a skimmer sock that is
I used them last year some, but have been using them almost every day this year and I did not think water could get CLEARER than what I thought was perfectly clear already. If the pump is off and there's no ripples on the surface it's almost like the water is invisible. I can see details on the bottom of the pool.... every minute wrinkle, blemish in extreme detail.... almost like there was no water there.
Even though dollar store 12 pairs generic hose is cheap, I've still been reusing them a couple of times before tossing. I'm mainly getting bugs and pollen so when I replace one I let it dry in the sun and the crud just falls off. I'll reuse it once or twice... eventually it gets runs and tears pulling over the skimmer basket.
You just have to check the pool more often though as they can get dirty pretty quick and start to deform the skimmer basket under the increased pressure. Pollen is letting up a bit around here so I can go a day with one.
