Motivation
Salt-water aquariums evaporate significant amounts of pure water. The salt contained in the salt-water does not evaporate. If evaporation continues, salinity of the salt-water rises to a level higher than in natural sea-water. Furthermore, cleaning devices like protein skimmers require a nearly constant water-level in the aquarium.
Implementation
The refill control refills fresh water from a separate tank to the aquarium.
- The water level is monitored by means of a water level sensor.
- The refill control actuates a pump if low water level is indicated.
- The refill control considers potential failure of the water level sensor (stuck at low, stuck at high).
