Great product, easy set up and functionality. Does exactly what it needs to do and I couldn’t be happier with this product.

It works as advertised. Although, the hose holder clamp came with the wrong plastic screws and it would not attach to the tank securely and I had to change the method as to get it stablely attached to my tank. It Loses 2 stars for my troubles.

Das ATO Gerät erfüllt voll und ganz seinen Zweck. Einfache Installation und keine weitere Bedienung von Nöten, außer den Wasser Vorratsbehälter nachzufüllen. Leider funktionierte nach einiger Zeit der untere Sensor zum Wasser einlassen nicht mehr korrekt. Habe mich direkt an F Zone gewandt und mein Problem geschildert. Ohne wenn und aber wurde mir anstandslos eine neue Sensoreinheit zugesandt. Das nenne ich Service, ganz GROSSES LOB. So etwas wird immer seltener und bleibt die Ausnahme.Vielen Dank an F Zone und deren freundliche Mitarbeiterin.

Prodotto di buona fattura, la pompa è abbastanza piccola da poter essere inserita in una tanica ma potente, gli agganci al vetro sono in acrilico trasparente ed universali per qualsiasi spessore del vetro.Una volta settato fa egregiamente il suo lavoro, va però valutata la durata nel tempo. Numerosi sistemi di sicurezza implementati per evitare che la pompa funzioni a secco oppure che un malfunzionamento faccia traboccare l'acquario. Led di stato sempre visibile, anche abbastanza forte.

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.

This is a handy little ATO. The hose holder is a bit flimsy and will not fit my rimed tank. I tucked it under a filter, and it works well.

I have several small reef tanks (12, 25, 40 gallons) and this works great to keep them topped off. Don't pay $150 or more for "a fancy one". Simply position the sensor in your return pump chamber where you want the high water line, put the pump in a reservoir and plug it in.No troubles with a five foot lift, silent operation, recovers from overfills gracefully. After good luck with the first one, I bought two more. PROTIP: if you don't need something this fancy, try https://www.amazon.com/gp/product/B08YD5HW29 which is great especially for smaller tanks.

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

Upgraded my ATO from the previous version. The package arrived on time, and the instructions were easy to follow. I like the smaller profile on this ATO than the previous version. It's much smaller than other brands; it can fit basically anywhere on your tank or in your sump without taking up space. I put mine in the sump, and I like that the sensors are on the inside of the sump glass. It's pretty much a plug and play: you just line up the water line (to be in between the high and low sensors) and then raise it just a touch, and then turn it on! The pump is definitely quieter and the tubing is slightly larger as well. Definitely recommend for all skill levels.
