Auto Top Off System Aquarium Ato Water Filler System Fish Tank Thermometer Aquarium Thermometer Sitck On

DIGITEN ATO System The ATO system uses a double float water level switch (like two eyes) to double monitor and protect the fish tank water level. The controller integrates a relay and a stable circuit to protect the water pump and the water level switch more effectively. The mounting holder is very firm which can freely adjust the water level up and down and it will not cause the water level switch to misjudge no matter the swimming fish water plants and so on. The whole system is very easy to install saving a lot of tedious work for DIY. DIGITEN Fish Tank Thermometer DIGITEN digital aquarium thermometer is designed for monitoring and checking the inside temperature of fish tanks and terrarium. With a large LCD transparent display a compact design it can help to make your pets live in a comfortable environment.
