Fzone Aquarium ATO Auto Top Off Refilling System with Pump, Aquarium Water Refiller with Dual Optical Sensor, Upgraded QST Tech and Smart ETFT Algorithm for Both Reef and Plant Tank

It is working okay, so basically does the job, The instructions a little hard to follow so find a YouTube video to help

Great product although had problems at first but they sorted it out and the product works fine highly recommend 👍

First time I used a fzone product , was setting up my 75gallon tank and decided with the air on it’s best to get a ato system so I went with this one , the quality of the parts is great no issues at all and the sensor works perfectly . Very easy to setup and very easy to wire up the pump is very strong for its size and you can feel the weight and build quality is high ( I have a few pumps this size and none compare with power and feel ). Seems like I need too look into there other products aswell

Lasted a grand total of 1 month, first and last fzone ato for me. I am now waiting to see if the seller will sort it out, I will update if and when it's sorted. I'm pleased to say that the supplier has sent a replacement pump, and the ato is working as it should

This looked like great value for money and quality for my reef tank ATO. Unfortunately it proved to be unreliable. Through the night the ATO water tank emptied. Rather than simply switching off like any other reliable ATO system it continued to run with the motor getting louder and louder - For the size of the motor the noise of it was like a motorbike in the livingroom. 4am and it could be heard loudly from bedrooms! By the time I got to it I could feel the heat building up with it running dry. Very dangerous to not have any/a reliable safety switch off built in. Stick to the big brands for reliability ans safety!

This is a great ato for a marine tank. At first I was skeptical due to the negative reviews but it was so easy to set up and we've not had any problems. It does the top-up without us noticing due to it being so quiet and the led lights really help if you do run into any bother. The only problem is there is no alarm on this but as I said not has any issues so far been using for the last 6 weeks

Reviewing this after about 6 months of use - This works perfectly, its easy to set up and hasnt failed yet. i fully trust this while im on holiday. It costs much less than my old ATO, even if it does fail i will buy again.

Didn't purchase through Amazon but this nifty device is a game changer. Not only good for fish tanks but reliable to keep any water topped up precisely with zero accidents and easy to use. Go away for days and aslong as you have enough water in the res it will keep that water level to your desired mark. If you don't have enough water in the res it will automatically turn the pump off when low.

Tres veces continúo bombeando agua aunque ya estuviera sobre el límite. Realmente peligroso. No es confiable y puede causar daños importantes

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

Flow is very strong and setup was a breeze. The sensor itself is very small so it doesn’t take up much space visually. Just make sure to use the included check valve so your tank doesn’t drain from the tube.

Fantastisch! Makkelijk aan te sluiten en werkt goed.
