Auto Top Off System- Smart ATO Lite Water Filler Refiller Advanced Water Level Controller w/Pump for Reef and Freshwater Saltwater Tanks Aquarium

I mean, I like the overall design and stuff, worked great for a lil bit, but by next morning it was stuck flashing in reboot mode, only when it was trying to refill too. The pump would turn on for a fraction of a second before turning off, tried unplugging it, moving sensor locations. . Nothing-update-The seller reached out to help resolve the issues, I did end up returning the previous pump and got a new one for free, and this one has been working without an issue! Sensor seems accurate and it comes with a generous amount of tubing, do be warned the LED is a bit bright though, definitely better for the sump.

Never have I come across a more reliable and efficient solution for managing water levels than this. The setup process was a breeze, thanks to the clear and straightforward instructions that left no room for confusion. Once installed, the system proved its worth with flawless precision, ensuring that my tank remained consistently full without any hiccups. What's truly impressive is the remarkable strength of the accompanying sensor's magnet, which firmly secures it in place, leaving no room for worries about displacement. This innovation has made my water management a hassle-free experience, allowing me to simply set it and forget it. Kudos to the creators for providing such a simple yet complete solution that has transformed my aquarium maintenance into a stress-free delight.

The first pump gave up in a week, so got a replacement, but the new one is barely pumping to keep the water levels. I have to manually top it off everyday. I have a 50 gallon tank, and also live in low humidity state, I think the pump can't keep up with all the refilling it has to do.The pump is very silent (when it works, lol), and the setup is easy to install. Would recommend for a smaller tanks (~30 gallons).Edit: the replacement stopped working too! Don't waste your money.

This ATO has been installed on a planted, freshwater nano aquarium for over a week without issue. You can easily spend a lot more on such as system, but I'm not certain its warranted.

I've been using this for a few months now and it's great! The biggest complaint from most people with other brands of ATOs is the beeping. If you want audible alerts, this isn't the one for you. No beeping! It's quiet and efficient. Keeps my reef tank right where it needs to be

Lasted 4 months.Edit: seller reached out and sent a new top off.

I love these ATO's, and more importantly, this is a great company to deal with. I bought 2 systems, and when I was having issues with one of them, several days later, when I contacted the company, they immediately offered to send me a replacement for no charge. It arrived a few days later, and now I am back in business.
