FZONENano Auto Top Off for Saltwater Aquarium and Fresh Aquarium

Works amazing and quiet

This can be set up and working in 5 minutes. Worked first time out of the box. If using with salt water, make sure your salinity is right before turning it on. I set my salinity to 33 ppt so as it evaporates it will reach 35 when it turns on, otherwise my tank would reach 37 ppt before turning on. Every tank and sump set up will be different but tuning this to never let your salinity get too high is the point, right?

I hope your aquarium is not in your bedroom because the light does not turn off. I'm buying a smart plug to turn it off at night. Hopefully that won't mess up the functionality.

This FZone auto top off system is fantastic. It arrives in a branded box with the ATO system well laid out right when you open it. Under that tray is the power connector as well as a length of tubing, manual, and some suction cups and accessories to hold the hoses and pieces in place.The auto top off system works by placing the sensor in the tank with the middle of the sensor at the desired water level you want to keep the water at. When the water drops below the middle, it begins to automatically fill up via the included pump. There are various LED indicator status which is described further in the manual to tell you if anything is wrong.One of the best features is that you can press the button to pause and resume filling, so that means I can pause it, do a water change and take out any water I need to, then press resume for it to automatically fill the tank back up.Overall, this is a fantastic system that is very reliable so far compared to others that I have tried. The included pause/resume function on this is also a major plus for me as I like to do water changes and don't want to unplug the entire ATO system and redo it every time.

Don’t buy this, it keeps malfunctioning everyday to the point I have to reset it every morning and it’s so annoying. Worst purchase ever, I spent about $61 on this order for nothing.

I’ve been struggling with evaporation in my 120L open Aquarium and this product has made that problem a thing of the past.Using an 18L slimline upright food container as the dechlorinated water reservoir and a smart plug (not required, but just for added safety incase the level sensor malfunctions) to control when it comes on and also to not have the blue light it emits in standby mode showing at night.Although not recommended I use it also to top up after 20-30% waterchanges by power it OFF/ON with the smart plug when topping up.Noise level is very quiet, pump power is great, build quality it good and functionality it ticks all the boxes as an ATO for my freshwater aquarium.Been using it 2 weeks now.

I have an update - it was missing the powerful magnet that holds the sensor to the glass. After contacting the supplier, they sent the entire unit again from a returned device. It had the magnet and that's all I needed. They went above and beyond to get me that magnet.I've been using it for about a month now and things are great.One suggestion would be to put some type of strain relief where the wires enter the solenoid. I can see the wires where they go into the solenoid. Eventually they will break. I used "hot glue" to fill the void and created my own strain relief.Previous Review:I've only had it for a week, but it seems to be doing OK.I've had other ATO's and they seemed to fail about every year or so. I decided to ty something else.I also eliminated my water reserve tank and opted for the RO/DI version and that freed up so much room under my tanks.Unless I'm missing it - I wish it had an audible alarm when something has gone wrong. Unless I look under the tank and see the red flashing I would miss issues.

The media could not be loaded. I ordered an auto top off to help with the evaporation in-between water changes. I have a ten gallon and it drops quite a bit where I have to adjust my surface skimmer. Everything was received as advertised and the pump was surprisingly small and compact. Assembly and set up was very easy. When setting up, the water level needs to be at or around the bottom of the sensor (low sensor). Then push and hold the controller until it goes "beep" "beep" which initiates the intialization process. This will pump the water to your desired level. Once at the desired level, the pump will stop and store that info in your controller for auto top offs.For water changes, push on the controller which will pause/resume the device.Super easy and very cool product. Controller lights also help with info on the auto top off device (overfilling error, no water in reservoir, etc )

Purchased this to keep my tank topped up while I was on vacation. It was very easy to set up, and I liked that the check valve had a flow direction clearly labelled. The sensor is very small and easy to hide. I hid the water tubing very nicely so it's hidden as well. The kit works great, setup was about 5 minutes and it's very self explanatory but does come with good instructions if needed for clarification. I haven't had any issues so far and don't expect any!

Ich finde das Teil super, da es immer die exakte Füllhöhe im Aquarium einhält und so kann mein Skimmer, auch bei einem längeren Urlaub, nicht mehr trocken laufen.

The media could not be loaded. Me voy 10 días y encontré mi salvación. Lo puse a prueba para ver si realmente funciona, una semana antes de irme, para no tener sorpresas y funciona muy bien. En cuanto baja un poco el agua, ya empieza a rellenar. Puse un cubo de 10L para la prueba, pero tendré que comprar uno más grande, ya que en verano y con el acuario destapado, se evapora el agua.Dato importante : Los dos sensores tienen que verse entre sí para que funcione.

Tres bon produit, très simple très fonctionnel très discret et très pratique.Rien à redire le nouveau modèle est excellent avec le bouton pause pour l’entretien de l’aquarium.Je m’en sers aussi pour remplir mon bac je mets beaucoup moins d’eau partout je ne regrette pas du tout, à voir si il tient dans le temps maintenant j’espère

The media could not be loaded. 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.
