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!
