Fzone Aquarium ATO Auto Top Off Refilling System with Dual Optical Sensor for Both Reef and Fresh Tank （360P)

This is my first time using an ATO system, and I set it up on my 65-gallon tank with a 5-gallon reservoir. Installation was pretty straightforward if you've worked with aquariums before. It works exactly as advertised so no complaints there.

Unit works great for my tank. Install was a breeze and unit is overall quiet.

Bought this because my previous ato (prism) just would not start anymore, after 2 years of doing what I need it to do. The first fzone came and just wouldn't work from the start, so I got a replacement. After getting the replacement and tuning everything to work I was getting fresh water into my display tank again. The problem was every time I would need to do a water change and had to turn my ato off I would get red and blue flashing light when turning it on again. So I would have to do the set up process all over again which was just a pain. I would have to turn everything off and hope the fzone would work. After changing the water 3 days ago and doing what I have been doing for the past month or so just to get this thing to work, well this time the fzone just would not work anymore it stays on red and blue flashing light will not engage the pump will not fill my tank back up. When you buy equipment in this hobby you're looking for things that make your maintenance easy and are reliable this product isn't it. Skip this one don't take the risk find a better replacement maybe I'm the unlucky one but going. 0-2 seems a little more than coincidence

Bought the first one 1 year and a half ago, now have one on all three of my tanks. Work great, good price have not had a problem with any of them. Highly recommend !

I can only give four stars for a couple of reasons. One is sometimes they don’t turn on when they are supposed to and they don’t always let you know when the water supply tank is empty. It’s supposed to flash red and turn off the pump but more than once I have found the pump running with no water. Just to let you know I have 4 of these and only two are acting up like this. They were past the return date by one week when I started having these problems. Can’t neither recommend nor not. Just purchase at your own risk and hope if it gives you problems that it’s within the return time limit.

I've bought 3 of these over the years. They are very good ATOs but the new pump is a disaster. The older pump (which was smaller) is a powerhouse and very reliable. The new one seems to get stuck on a weekly basis and can even burn itself up, even though it is sitting in water! I've gotten the replacement part and it's the exact same pump with the exact same issues. Please go back to the older pump or find a better supplier!!!

This works great with my tank. Very easy to install.

Second one I've bought since the other one worked so well in my other tank.

Lo utilizo para mi acuario marino y la verdad ni un sola queja. Funciona a la maravilla desde el primer día.

Perfect a must for every marine tank

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。

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!

This system was the one that I have been looking for for a long time! It works like a charm and I don’t have to worry about my tanks going too empty. Installatiin is super easy and maintenance is very easy to do!
