## Description

Product description Package Include ATO Controller *1 DC refill pump *1 Universal tube holder *1 Water check valve *1 Power adapter *1 PU tubing(6.5ft) *1 User manual *1 Mini size: only 0.7 inches. Suitable for rimmed/rimless nano and medium aquarium tanks. Dual optical sensors and upgraded ETFT (Extra Time Filling Technology), AFT (Anti-fluctuation Technology), and QST 2.0 (Quick Security Technology). Safe and precise Updated check valve,instead of siphon break, prevent water backflow from tank. Power : AC 100-240V/50-60 Hz input, DC 12V/1A output. Power cable length: 6ft(180 cm) Sensor precision: 1mm Pump head: 6.56feet (200 cm) Pump flowrate: 74 gph (270 lph) Max. Mounting Thickness : 15mm Length of Cable between Sensor and Controller: 4.92 feet (150 cm) Tubing: 6.5fee, 9/12mm diameter. ETFT(Extended Time Filling Technology) ETFT(Extended Time Filling Technology) is our own patented algorithm. During the initialization process the controller recognizes the tank size by timing how long it takes to fill the water from "Low" to "High" position; That time is called ETFT(Extended Time Filling Time). In normal refilling, the device fills the water to the LOW position and continue pumping for a circle until the water level reaches about "LOW" but never goes above "High". Precisely keep the water between the LOW and the High sensor positions. This unique feature allows extra time of rest between refills, can substantially increase the products's life span. AFT(Anti-fluctuation Technology) Most ATOs in the market start and stop the water pump too quickly due to the water level fluctuation cause by many factors such as feeding, livestock,etc. The frequent start and stop will shorten the pump's lift span and efficiency. Our smart ATO 360P uses AFT to identify and recognize any false water fluctuation; It only starts the pumps when the level is truly low. QST(Quick Security Technology) V2.0 The controller uses QST for real-time protection against overfilling and flooding. The controller will give a visual alert and stop the pump immediately when it senses a refilling time more than 6 times longer than the ETFT. QST can detect a malfunction of the sensor or the controller or an empty reservoir. In version 2.0 we incorporate ETFT feature and not relying on first filling time from version 1. Our ATOs are far safer. Flooding barely happens when following the instructions carefully. Selecting the Perfect Auto Top Off Model for Your Aquarium

Review: Funciona perfectamente - Lo utilizo para mi acuario marino y la verdad ni un sola queja. Funciona a la maravilla desde el primer día.
Review: 期待通り - 4月に購入して半年以上使用しましたが、30cmキューブ水槽で問題なく稼働しています。 冷却用のファンを付けているので毎日1センチ程度は水位が下がりますが適宜反応して給水しており、12Lのタンクに繋いでおおよそ3週間程度は持ちます。 半年間で赤点灯で給水しなくなるエラーが3回ありましたが、いずれも電源の抜き差しで復旧しており、今のところ給水が止まらない障害は起きていません。 水換えの時にセンサー周辺を掃除しないと苔により反応が悪くなるようで、完全にノーメンテとはいきませんが、毎日の足し水と比べたら相当な手間が省けます。 しいて言えばエラーの原因が不明なので少し不安は残りますが、1週間以上様子を見れないような状況でなければ問題はないかと。 同じ仕組みを自作しようとしても価格程度のコストは掛かると思いますし、似たような製品が少ない中で高値でもなくおすすめできる商品だと思います。

The ATO controller will give a visual alert & stop the pump immediately when it senses a refilling time more than 6 times longer than the time calcualted by EFTT. QST will detect malfunctions of the sensor, controller or if you have a empty reservoir. Version 2.0 includes new technology making our ATO’s the most safe option.

## Questions & Answers

**Q: Any time the pump looses power and reboots when it gets power back does it have to refill all the way to top line for measurement? Or is it a one time**
A: Yes it has to refill to the top sensor so it can recycle, also if water level goes way below sensor when it reboots it will only pump 3 times then red light comes back on so unplug and plug back in so it can pump remainder water to reach level you might have to do this several times( i hope not) usually once is sufficient, hope this helps.

**Q: Can I use it on a 40 gal ?**
A: Yes, it will work fine.

**Q: Will this still work if I put a longer tube on it?**
A: Sure

**Q: How do you install hose clamp on a rimmed tank?**
A: Just rotate it. It will fit.

### ⭐⭐⭐⭐⭐ Ottimo Prodotto
*by L***A on 13 June 2023*

Il prodotto arriva correlato d’ istruzioni in Inglese, il montaggio è estremamente semplice, sul sito è presente anche un filmato illustrativo, in pratica non ci si può sbagliare. I cavi di alimentazione ed il tubo d’immissione dell’acqua risultano molto lunghi e quindi posizionabili dove si vuole. E’ presente anche un’utile valvola di sicurezza per il non ritorno dell’acqua, l’aggancio alla vasca del tubo d’immissione avviene tramite un supporto curvo a 2 viti in acrillico nel mio caso si è adattata perfettamente all’acquario con spessore di 6mm, penso che per come sia strutturata sia adattabile ad ogni spessore. La pompa è micronizzata ed è entrata perfettamente nel collo della tanica che normalmente uso per il rabbocco, pur essendo molto piccola non inficia sulla potenza, spinge forte ripristina il livello in pochi secondi. Il sensore è molto piccolo piu o meno come una moneta da un’euro l’ingombro in vasca è praticamente nullo, viene tenuto in posizione tramite una calamita che deve essere posizionata sulla parte opposta del vetro (vedi foto) , la calamita è molto forte ed il sensore non si sposta da dove è posizionato. Il led di stato si fa notare d’altronde è quello il suo scopo, penso che se dovesse dare fastidio si può pensare di attaccare lo strumento ad una presa temporizzata (impiega veramente poco a ristabilire il livello). Per quanto mi riguarda avendo una vasca aperta e visto l’innalzamento delle temperature non devo più preoccuparmi del rabbocco e posso lasciare l’acquario tranquillamente anche per giorni. Al momento non ho da segnalare difetti e sono soddisfatto dell’acquisto!
