{"title":"AutoAqua","description":"\u003cp\u003eFounded in Taiwan in 2011, AutoAqua specialises in one thing, optical sensing for aquarium automation. Its Smart ATO units, ATO meaning auto top off, watch the water level with an optical sensor that has no float to stick, then pump fresh water from a reservoir as evaporation drops the level. The Duo and Lite suit sumps and standard tanks, the G2 Nano hangs on a small tank, and the Smart ATO RO opens a solenoid to fill a storage drum from an RO line. The Security series applies the same sensor to protection: Skimmer Security cuts power before a cup overflows, Level Security stops a rising level, and Temp Security disconnects a stuck heater. An inline TDS meter, the ASOV shut off valve and the Smart Stir stirrer complete the set.\u003c\/p\u003e\u003cp\u003eIn a reef tank, top up with RO water rather than tap water.\u003c\/p\u003e","products":[{"product_id":"auto-aqua-dc-solenoid-valve","title":"Auto Aqua DC Solenoid Valve","description":"\u003cp\u003e\u003cstrong\u003eFeeds top-off water straight from the RO line, with no refill pump to fail.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe AutoAqua DC Solenoid Valve (SV-12V) replaces the submersible refill pump on an AutoAqua top-off or water-change controller.

It runs on 6 W at 12 V DC taken from the controller's pump socket, joins the line with quarter-inch push-fit RO tubing, and operates on any supply between 0.02 and 0.7 MPa.

The collection cup wall must be within the published magnetic mounting thickness so the sensor can clamp to it, and the skimmer pump must draw under 10 amps, which every aquarium skimmer does. The unit switches mains power to the pump, so it is indifferent to the skimmer's brand, body design or whether the pump is AC or DC.\u003c\/p\u003e\n\u003ch4\u003eDo I have to reset it after the skimmer trips?\u003c\/h4\u003e\n\u003cp\u003eNo. The unit has an auto-recovery function: once you empty the collection cup and the sensor is clear, power is restored to the skimmer without pressing anything. A power-on delay holds the skimmer off briefly before it restarts.\u003c\/p\u003e\n\u003ch4\u003eWill it false-trip every time the foam surges?\u003c\/h4\u003e\n\u003cp\u003eIt is designed not to. AutoAqua builds a detection delay into the Smart Security range specifically so a momentary splash or a passing bubble does not shut equipment down, and a separate power-on delay so the skimmer does not restart into an unstable state straight after a blackout.\u003c\/p\u003e\n\u003ch4\u003eHow much power can it switch?\u003c\/h4\u003e\n\u003cp\u003eThe unit is rated 100-240 V AC at 10 amps, which AutoAqua states as 2,200 W at 220 V AC and 1,100 W at 110 V AC. On Australian mains that is roughly 2,200 W — far more than any aquarium skimmer pump requires. It should still be used to switch the skimmer alone rather than a powerboard of equipment.\u003c\/p\u003e\n\u003ch4\u003eHow long is the sensor cable?\u003c\/h4\u003e\n\u003cp\u003eThree metres, which AutoAqua also lists as 10 feet.

Use the supplied 4 mm internal diameter tubing with a 1\/4 inch connector between the two.\u003c\/p\u003e\n\u003ch4\u003eDoes the Smart ATO nano G2 have an audible alarm?\u003c\/h4\u003e\n\u003cp\u003eAutoAqua documents a flashing red LED when the QST protection trips and the pump stops. No audible buzzer is published for this model, so treat it as a visual alert. The Smart ATO Duo is the model in the range with a documented audible alarm.\u003c\/p\u003e\n\u003ch4\u003eWhat rim thickness does it hang on?\u003c\/h4\u003e\n\u003cp\u003eThe hang-on holder fits a rim or glass panel between 3 and 10 mm thick. The sensor magnet separately works through glass up to 12.7 mm, so the two limits are not the same number.\u003c\/p\u003e\n\u003ch4\u003eCan the pump be replaced on its own?\u003c\/h4\u003e\n\u003cp\u003eYes. The DC diaphragm pump is AutoAqua part DP-1212C and is designed for toolless replacement, so a worn pump does not require a new controller.\u003c\/p\u003e","brand":"AutoAqua","offers":[{"title":"Default Title","offer_id":55242297737507,"sku":"BA8469","price":149.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/autoaqua-smart-ato-g2-nano-43508248281379.webp?v=1790234313"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/collections\/autoaqa-smart-stir-3000773-1600.jpg?v=1788252552","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/collections\/autoaqua.oembed","provider":"Nicks AOT","version":"1.0","type":"link"}
