ATO systems are very important on saltwater aquariums and can give you more success, and time to enjoy your tank. Aquamedic's Auto Top Off System Pro is a well thought out, plug and play design that incorporates every aspect of a safe and reliable ATO system.
- Water resistant controller
- Optical water level sensors
- Backup level sensor
- Empty reservoir sensor
- Dry-run protection
- Audible and visible alarms
- Low voltage
ATO systems are easily one of the most important pieces of equipment on a saltwater aquarium. By keeping your tanks water level steady you will also benefit from a constant salinity, not to mention the daily task of adding water to the aquarium or sump will be removed.
Aqua Medic's Auto Top Off System Pro is a well thought out, fail-safe design that uses multiple sensors to monitor the fluid level of your aquarium, and also warns you when your top off reservoir is getting low. The ATO Pro utilizes an optical sensor as the main level sensor to continuously monitor the water level and has a backup sensor that goes above the optical sensor. The entire ATO system will shut the system down if water ever gets too high and triggers the backup sensor.

Easy to use, simple set up By Al on 2/6/2019Al would recommend this product to a friendThis product has worked as advertised for years now but there are a few things to note:
1) it does require periodic cleaning on the sensors to clear salt creep or other junk
2) the sensor in the fresh water tank has suction cups that rarely stay secured to the bottom, not a huge deal but the level can't get as low as it could before the alarm goes off when the sensor is floating slightly
3) Wtih the the system turned off, it will siphon water from the fresh water tank to the sump if the water level in the water tank is above the level in the sump. This will continue to happen until they are equal or the fresh water tank level is lower than the sump level. Keep this mind when selecting your fresh water tank and where you place it.
Unreliable Sensors and HORRIBLE Customer Service. By AH on 12/3/2018AH wouldn't recommend this product to a friendThis is a sweat compact little system but unfortunately the sensors are cheap and unreliable. I have to pour RO water over them each morning. Contacted AquaMedic for support to try to troubleshoot my unit. Initially I got a response, I was asked for additional information which I provided and then company literally blew me off. I initiated another contact with the company. I was given an apology that was immediately negated with a lame excuse for the blow off. I was asked to provide my address so Aquamedic could replace the sensor. Address was provided but the sensors were never mailed to me. Been waiting for several weeks now! In the process of looking for a new ATO. Won't buy this one again.
Have had for over 2 years 0 issues By Steve on 8/12/2018Steve would recommend this product to a friendNot sure why all the negative reviews. I have had this ATO for over 2 years and it has never missed a beat. In the very beginning I had trouble with it over filling until it hit the emergency sensor. I called BRS customer service and they told me most likely the issue was the optical sensor was collecting bubbles, making the sensor think it was out of the water. That was the exact problem. After I resolved that issue it has been rock solid. I also like the alarm letting me know when my top off reservoir is near empty. When the alarm is sounding, the pump will not run, preventing the pump from burning out. In conclusion I recommend this product.
Glitchy By Josh on 3/20/2018Josh wouldn't recommend this product to a friendThe unit I received works fine until the reservoir runs out of water. In these situations I have to unplug the ATO before filling the reservoir. For some reason the pump with stay on and empty the reservoir if I refill the water with the ATO, it does not respond to the sensors.
Unreliable By Ian on 1/7/2018Ian wouldn't recommend this product to a friendThis ATO system seems to be working well so far in every way except for the primary water level sensor. When I first set is up, water from my reservoir filled up past the first sensor and only stopped when it hit the backup one. Only later after fidgeting with the system did I get it to work, and only then for a couple of days. I guess this product is hit or miss because some people seem to be having no problems with it while others seem to hate it...
Unreliable By Rob on 12/25/2017Rob wouldn't recommend this product to a friendSensor seems to be faulty or poorly operational and keeps the pump from shutting off way over the black small box sensor.
Unreliable By James on 9/7/2017James wouldn't recommend this product to a friendI'm currently on my 2nd unit. From the beginning the first unit would randomly stop working. Would take a bit of fidgeting to get it to work again. First it wouldn't fill the reservoir then when it started running it wouldn't stop until the water reached the little black emergency shut off box. I contacted AquaMedicwho responded quickly. I contacted them a day or so later to let them know the unit had started working again. A couple of weeks later I contacted them again to let them know the issues had started again. A week goes by with no response. I contacted again and was told they contacted the manuf in Germany and that it takes a while to get a response. Two weeks or so goes by and a package appears at my door. The new unit worked perfectly for about a month and started randomly stopping to work. I discovered if I use a turkey baster and spray the sensor with water it will eventually start working. So far over the last two weeks it's stopped working 3 or 4 times.
Excellent Product and Excellent Customer Service By Kevin on 3/16/2017Kevin would recommend this product to a friendThis is an excellent product with not only the optical and back up sensor for the sump area, but also includes the float sensor for the ato receptacle. On top of that, the customer service at AquaMedic is excellent. I highly recommend this product for anyone.
Hi! I was just wondering if this ATO could be mounted in a display tank, as I have no sump at the moment. The attachments for the sensors seem to be very far down in the pictures.
What is minimum water depth in sump required for this system
