The TMC Auto Top Up is a brilliant innovation for keeping your aquarium topped up and helps with evaporation, it uses a mini pump in your reservoir. Unlike many other top-up devices, this utilises a float and mini pump to pump the water into your aquarium. All you need to do is put the pump into your reservoir, run the tube and wire from your reservoir to the tank. It easily fixes in place and when the float switch detects the water is too low, the pump begins.
The benefit of a float switch over a digital tracking method is its both highly accurate and won't fail you. once the touches the base it triggers the pump to turn on. Perfectly simple and always reliable.
The float switch comes complete with a compact energy-efficient 200l/hr pump. Whilst compact this pump is highly efficient and reliable making it perfect for topping up your aquarium up when your not around to do so.
Two float switches for peace of mind, one float switch for regular use and the 2nd float switch as a back up feature.
