Review on 🐠 Malida Power-Free Water Level Controller - Automatic Aquarium Water Filler, Auto-top-Off, Marine Water Changer, Float Valve, Vacuum Regulator - Ideal for Adding Water by Andy Baker

I just bought it and installed it in my aquarium sump. So far it looks good and comes with multiple 1/4" fittings, a valve and hoses. You can adjust the height of the float and the float itself. The height adjustment requires some finesse and a Phillips head screw is used to adjust the float. Use one of the supplied fittings on the float and then connect the hose to the fitting, so far that's good.
