Now Includes Siphon Break

One of the smallest all-inclusive auto top off systems on the market today. The Micro ATO includes an optical water level sensor to keep an eye on the level within the sump with no moving parts. The optical sensor is very reliable, even in complete darkness, keeping a steady water and salinity level replacing any evaporated water with fresh water. The Micro ATO, like its predecessor, uses a magnetic mounting solution that works for tanks and sumps that have up to 1/2" thick walls.


An auto top off system is one of the first automated devices any reef keeper should have. When water evaporates, the salt is left behind slowly increasing the salinity of the tank. By utilizing an ATO device evaporated water can easily be replenished by the top off unit throughout the day keeping your tank's salinity very stable. Most of the time the location where the sensors need to be placed can be very limited in space.


AutoAqua has released their Micro ATO system making it the smallest auto top off unit on the market today. The downfall for most top off systems is the float valve or moving parts. AutoAqua utilizes an optical sensor to visually look at the water level. With the magnetic mounting of the optical sensor placement options are limitless while if the magnets are ever to slip or the sensor gets knocked and moved, the Micro ATO provides a real-time fail safe protection against such instances.


The siphon break needs to be mounted higher than the water level, and within the ATO reservoir to function properly. Water dripping out the hole when the pump is on is normal.
