Hahaha! Yup, better get your own measuring cups!

My dedicated pool maintenance supplies include a 2Q and a 1C plastic measuring cup, a toothbrush, a pot scrubber, a scotch sponge with delicate scouring pad, a plastic turkey baster, a roll of paper towels, a plastic long-handled spoon, and 2 buckets: one small, one large.

You can include the box of DE in your will. It may last longer than you will! Cheap, though, and worth it.
