## Description

The ATO system automatically maintains the water level in the aquarium, ensuring a stable and healthy environment for aquatic life.

Review: Only Reliable option - I have tried electronic float switches on relays and gravity floatswitches that work without power and have the water damage to prove it. This item is the only method I've found for having a foolproof topoff system that does not fail. The alarms for pump running longer than average is nice sometimes but sometimes annoying depending on your use case. The included hosing and pump just seal the deal for this being the best aquarium item for automation. I wish the sensor was able to be placed a little closer to the rim but because it can only be oriented with the wire coming out of the top it can't sit flush, but I've made due for many months and still appreciate the work this system puts in for me.
Review: MOST AQUA - THESE ARE GREAT. I BOUGHT ONE FOR A TEST AND I NOW HAVE THREE! THE ONLY PROBLEM IS ONE IF MY TANKS IS 126 GALLONS AND THE GLASS IS ALMOST TO THICK FOR THE MAGNETIC SYSTEM TO WORK ON THE LASER. BUT IT DOES I JUST HAVE TO BE CAREFUL NOT TO KNOCK IT LOOSE. I AM 65 AND IT IS TOUGH FOR ME TO LIFT WATER INTO MY TANKS. WITH THESE I USE A LG PLASTIC TRASH CAN AND DUMP IT INTO IT. A PIECE OF CAKE. AT 85 I NEED ALL THE HELP I CAN GET! BILL HALE

### ⭐ Garbage! I'm tired of coming home to a flood!
*by M***S on September 25, 2024*

I'm sorry, these are just garbage. I ordered a total of three of these all within about the last 10 months, and none of them worked out for me. One that I ordered was missing the magnet that holds the sensor to the tank out of the box. One just flashes blue when the water level drops low, but the pump never comes on. I have cleaned the sensor and the pump, and even swapped the pump entirely, but the unit doesn't pump, it just flashes blue. And the last one, and maybe most importantly, this one very reliably will come on when the water level drops low, but will at random times inexplicably keeps pumping and pumping water until it depletes my ATO reservoir and floods my saltwater tank. This rapidly lowers the salinity of the aquarium to dangerous levels where I've had livestock die, and then saltwater from the tank is forced out, making a huge, huge mess. This has happen now three or four times at least in my short time having this ATO. I'm an simply sick of coming home to floods!!! I reached out via Amazon to the seller for help or for a possible warranty exchange, and I heard nothing in return but crickets. I will no longer trust these budget ATO's, I'll spend the extra on a name brand unit.
