FZONE Auto Top Off System with Independent Controller - Dual Optical Sensor ATO with Visual Safety Alarms & 74 GPH Pump for Saltwater Freshwater Aquarium

Great product with useful features. Easy to install and works very well. The low resovior water warning light is a great touch.

Bought this a few months ago and thought it was time for a review.Nice small optical ATO that has proven to be very reliable on a small nano reef tank. Easy to setup and and absolutely trust worthy. Snall pump is pumping RO water about 1 metre up with ease.Overall, a great value and trustworthy piece of kit!

works fine for couple of days then turns itself off meaning have to restart it.Edit. Seller sent me out a new unit. Works perfectly now thanks v much.

I found this to be unreliable. I returned it once due to a defect and the replacement worked okay for several months and then ceased to work. Before doing so, it overflowed my aquarium! The water level it maintains tends to get wider and wider. There is also the issue that if there is a power cut, the settings are reset and it will not operate, so one cannot leave it when going on holiday with much confidence. It is overly complicated and unreliable. I have replaced with a Tunze unit which maintains a consistent level and if there is a power cut, it will not affect it, it will just start operating again when the power returns. I have yet to see how reliable the Tunze is as I've only had it running a month, but being German made and with a 5 year guarantee, I suspect it will be superior. It would be hard-pressed to be worse!

Only problem that’s shown up is the tubingCould do with a kink free tubingSorry to say Had to buy some new tubing as supplied item not fit for purpose .That apart easy set up and level warning if water level is wrong .

It comes neatly packed, everything feels high quality.Setting up is simple thanks to the clear, well organized installation manual. Whether you need a temporary solution for holidays or a permanent fixture, this top off system delivers. It features a convenient one press pause button for water changes and operates in near silence.

Fitted easily. Works as expected. Hopefully works long term.

I received the ATO and immediately installed it onto my aquarium. I was surprised at how easy it was to install and setup, with the instructions being very clear and easy to follow.Over the next few hours I continuously tested the device purposely dropping the water level making sure it wouldn't over fill as others I've owned in the past had done.To summarise my experience with this ATOAmazing build qualityEasy setupEasy InstallWill be buying more for my other tanks in the future.

Avendo in casa diverse vasche nel periodo estivo mi trovo a dover rabboccare l'acqua evaporata, se la vasca è piccola ci si sta dietro ma quando questa è grande diventa un vero problema.Per tale scopo ho acquistato questo sistema di rabbocco automatico, l'ho testato appena arrivato simulando una evaporazione minima e devo dire che dopo che l'acqua è scesa di pochi millimetri, il sistema ha attivato la pompa per ristabilire il corretto livello, ho ripetuto diverse volte questa prova e il sensore è sempre intervenuto in modo preciso.La pompa l'ho immersa in una tanica da 20 litri essendo piccola per mia fortuna è passata dal foro del tappo, la pompa riesce a spingere l'acqua tranquillamente nella vasca nonostante sia a livello pavimento.Nella confezione c'è tutto il necessario all'installazione, non manca proprio nulla, quindi che dire il prodotto è perfetto, completo e allo stesso tempo funziona bene.Dimenticavo lo utilizzo anche per i cambi settimanali d'acqua così non porto più su le taniche e fa tutto lui in automatico e la mia schiena ringrazia.

No funciona bien. Se suspende a cada relleno aún teniendo agua el depósito. Debes estar muy al pendiente a que no se suspenda (ponerse en rojo la luz), es lo mismo a estar rellenando en modo manual.Tendré que comprar otro que sea seguro en su funcionamiento.

Das Nachfüllsystem hat 6 Monate super funktioniert, bis ein Wackelkontakt im Sensor auftrat.Der Sensor wurde anstandslos ausgetauscht, auch der Support des Fzone Service hat sehr schnell geantwortet. Bin sehr zufrieden und kann das Produkt auf jeden Fall weiterempfehlen.

Installation facile avec un manuel clair (même si en anglais, on s’y retrouve rapidement). Les deux capteurs optiques fonctionnent parfaitement et permettent de maintenir un niveau d’eau stable dans l’aquarium, avec une sécurité fiable pour éviter tout débordement.Le système est silencieux, la pompe est efficace et le boîtier est simple à utiliser (un appui long pour l’initialisation, très pratique).Bon rapport qualité/prix, je recommande pour tout bac planté ou récifal qui a besoin d’un niveau d’eau constant.

製品は良いと思う。日本の代理店？の対応は塩www日本語の取説が無いので勘でセット出来る人用20×20×30hのネオグラスエアに使用しました。外掛けフィルターに植物を入れ、水草が水槽から飛び出ている為、蓋なし運用となり水の蒸発が早い為、頻繁に足し水をする必要がありましたが自動給水となり、手間要らずとなりました。24時間に1〜2回程度の足し水回数の様です。
