controller and power source?\u003c\/strong\u003e\u003cbr\u003eYes. The sensor plugs into a HYDROS Control Sense Port for power, and your skimmer must be plugged into a HYDROS power source (like the WiFi Power Strip or Smart Plug) so HYDROS can switch it off. Both are sold separately.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill it fit my skimmer?\u003c\/strong\u003e\u003cbr\u003eIt works with any protein skimmer collection cup that has walls up to 1\/4 inch thick. The magnetic mount holds it in place without a new lid or any modification.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this for saltwater tanks?\u003c\/strong\u003e\u003cbr\u003eYes. Protein skimmers are used on saltwater and reef aquariums, and this sensor is built to keep that skimmer from overflowing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre there any moving parts?\u003c\/strong\u003e\u003cbr\u003eNo. It uses an optical eye with no moving parts, so there is nothing to stick or wear out.\u003c\/p\u003e","brand":"Hydros","offers":[{"title":"Default Title","offer_id":48194840035547,"sku":"21196","price":46.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/5209\/3403\/files\/image_329d9432-ccda-45bb-a912-98172e354711.png?v=1769532976","url":"https:\/\/squeakysaquatics.com\/products\/coralvue-hydros-magnetic-skimmer-sensor","provider":"Squeaky's Aquatics","version":"1.0","type":"link"}
