Without top off, your salinity climbs every single day. An auto top off senses the drop and adds fresh water to compensate, automatically.\u003c\/p\u003e\n\u003ch3\u003eDoes the Level-O come with a reservoir?\u003c\/h3\u003e\n\u003cp\u003eNo. The box holds the dual laser optical controller, the power supply, the pump and 7 feet of tubing. The freshwater reservoir sells separately — Reef Casa's The Well, 5 gallons, is built for it.\u003c\/p\u003e\n\u003ch3\u003eWhat is dual overfill protection?\u003c\/h3\u003e\n\u003cp\u003eReef Casa fits two optical sensors instead of one. If the first lets water past, the second kills the pump. It's the single most important safety on an ATO: a system that fails to stop empties your whole reservoir into your tank.\u003c\/p\u003e\n\u003ch3\u003eWill it work on a tank that isn't a Reef Casa?\u003c\/h3\u003e\n\u003cp\u003eReef Casa lists it as working with its all-in-one models. The physical constraint to check is the thickness of the wall where the sensor mounts: half an inch maximum.\u003c\/p\u003e","brand":"Reef Casa","offers":[{"title":"Default Title","offer_id":47425054638251,"sku":"RC24241","price":129.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0513\/7108\/1899\/files\/Box-scaled.jpg?v=1784312770","url":"https:\/\/reefsolution.com\/en\/products\/reef-casa-level-o-ato","provider":"Aquarium ReefSolution inc.","version":"1.0","type":"link"}
