On Sunday our pool service guy, Al, came by to change out the sand in our filter tank. This is done every few years.

 The big round filter seems to have warped during the years it has been is service. The cap on the  top doesn't want to seal tightly and Al says the whole tank needs to be replaced. He estimates about $2,400 to replace it.

The old filter sand was placed next to the bulkhead. It is still unbleached like the rest of the beach sand. It is also much more coarse and does not stick to one's feet. At least that sand won't be tracked into my condo.
