A solid-state EC sensor with titanium probes drives a variable-flow pump rated to 300 L\/h at zero head and 2.5 m of lift, throttling back to around 72 L\/h near target level. It suits any marine sump or display within that head and flow range, provided you supply the reservoir and top-off water.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolid-state EC sensor\u003c\/strong\u003e — titanium probes with no float arm or optical window to jam, fog or scratch.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic flow throttling\u003c\/strong\u003e — the pump settles to roughly 72 L\/h near target level instead of surging at full flow.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndependent leak detector\u003c\/strong\u003e — a separate titanium probe disables Auto-Fill and stops the pump if it senses water where it shouldn't be.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackup high-level probe\u003c\/strong\u003e — a second trip point set roughly 2.5 cm above the normal pump-off probe guards against an overfill.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReefBeat app control\u003c\/strong\u003e — level and temperature history plus fault notifications over Wi-Fi, with up to 28 days logged.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eServiceable pump\u003c\/strong\u003e — the impeller and pump head are designed to be opened and cleaned, not replaced as a sealed unit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic mounting\u003c\/strong\u003e — sensor holder and tube clips attach to glass up to 12 mm thick without drilling.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eRed Sea ReefATO+ (SKU RED901)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eAutomatic top-off (ATO) system for reef and marine aquariums\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater level sensor\u003c\/td\u003e\n\u003ctd\u003eSolid-state EC technology, titanium probes, multi-input\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBuilt-in thermometer\u003c\/td\u003e\n\u003ctd\u003eAccuracy ±0.1°C, logged every 15 minutes for up to 28 days\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLevel control band\u003c\/td\u003e\n\u003ctd\u003e3 mm between pump-on and pump-off probes;

This warranty applies in addition to the consumer guarantees you already hold under Australian Consumer Law, which exist regardless of any manufacturer term. The included power supply plugs into a standard AU wall outlet; Red Sea does not publish a specific mains input voltage rating for the pack on its Australian materials, so check the label printed on the unit itself before use. The controller is for indoor use only and is not waterproof, so mount it clear of splash zones. Freight-wise it is classed as a standard parcel item, not oversize or special-order.\u003c\/p\u003e\n\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\u003ch4\u003eDoes the ReefATO+ include a water reservoir?\u003c\/h4\u003e\n\u003cp\u003eNo. It pumps from a container you supply. Use a sealed, food-grade container sized to at least a week of expected evaporation, placed within the pump's 2.5 m head and 300 L\/h limits.\u003c\/p\u003e\n\u003ch4\u003eCan it dose anything other than top-off water?\u003c\/h4\u003e\n\u003cp\u003eNo. It replaces evaporated water only. A separate doser is needed for trace elements, buffers or any other supplement.\u003c\/p\u003e\n\u003ch4\u003eWhat happens if the sensor loses contact with the water?\u003c\/h4\u003e\n\u003cp\u003eThe unit shuts the pump down automatically. The same cutoff also trips on an abnormally long pump run, a blocked pump, a dry reservoir, or a detected leak, and requires you to resume operation via the button or app once cleared.\u003c\/p\u003e\n\u003ch4\u003eIs the pump repairable if it wears out?\u003c\/h4\u003e\n\u003cp\u003eYes. Red Sea designs the pump to be serviced rather than replaced whole, though the impeller itself is a wear part covered for 6 months rather than the full 2-year warranty.\u003c\/p\u003e\n\u003ch4\u003eHow does the backup high-level probe work?\u003c\/h4\u003e\n\u003cp\u003eIf the normal pump-off probe fails to detect the rising water level, a second probe positioned roughly 2.5 cm higher cuts the pump before it can overfill the sump.\u003c\/p\u003e","brand":"RedSea","offers":[{"title":"Default Title","offer_id":54774162620707,"sku":"RED901","price":378.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/RED901_4.png?v=1772078912","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/red-sea-reefato-system","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
