## Description

Say NO to the expensive ATO!🎣 🐠The ATO system uses a double float water level switch (such as "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. 🐡The stable system saves you from worrying about overflow when you go out!🐟 We believe you will fall in love with this ATO!Specifications: Pump Material: PCABSRated voltage: 12VDC Max power: 5W, Rated current: 0.5A🐠Waterproof grade: IP68 Max lift: 0.4-1.5mMax flow rate: 200L/HNoises: Power adapter Input: 100-240VAC, Output: 12VDC, 1APump cord length: 1.4m (4.59ft) Power cord length: 1m (3.28ft)Splitter adapter cable length: 24cm (0.78ft)Silicone hose length: 2.5m (8.2ft)Dual float ball sensor cable length: 1m (3.28ft) 🐠NOTE: 1, Make sure the water level is higher than the pump, to prevent pumps from running dry and failing.2, Make sure all cables are plugged into the hole fully. 🐡Package include: 1 x Holder1 x Dual Float Ball Sensor 1 x Pump1 x Power Adapter1 x Splitter Adapter Cable 1 x Silicone Hose1 x Siphon Break1 x Manual.
