I don't like pool filter sand myself due to how fine it is (always seems to be #20 here in the US.) If you can find an abrasives supply company in your area they'll likely have something you can use. I personally use crushed glass (#10-#20) that's sold as a sandblasting abrasive rather than silica sand.
