Effective in Controlling Evaporative Loss

In salt water systems the loss of water from the tank is by evaporation is of fresh water only, which will increase the salinity within the aquarium. This can be automatically replenished using a float switch and controller such as the D-D Multi Function Float Switch System. As the float switch rises and falls it switches the controller on and off, which in turn controls a pump or solenoid to top up the lost water.
