Hi there! Based on your question about a sand filter lid, a few options from the PriceCheck search results popped out at me: The Filter Lid & Oring Set for R149 and the Universal Filter Lid for R159 seem like great choices as they will keep your sand filter working properly. The set and universal lid are specifically meant to fit on top of the filter and come with new orings to get a good seal. Let me know if you need any other details on those options! I hope this helps in your search.
