Boy, compared to you folks I must seem like a neanderthal!

I have been using the same sock since the beginning of May--and it's now June. I rinse it when it's dirty in a bucket till it's clean then back in the skimmer. Why dry it? It LIVES in water. I figure I will use this one till it doesn't rinse, or gets a hole, or the elastic no longer keeps it on the skimmer, then I'll switch. It's not that I'm cheap, I just haven't seen a reason to replace it yet.

I even add chlorine, baking soda and Borax through it.
