RED STARFISH Water level auto top off 4L

Red Starfish Auto top up system is designed to clip onto the top side of your tank (max glass thickness 12mm) with two hoses that lead down into your tank.  As the tank water level drops, water is automatically fed into your tank.  In marine tanks this helps keep the salinity at a constant value.  With 4 Liters of capacity this is perfect for marine nano tanks as they can be sensitive to salinity changes due to evaporation. Simply add fresh RO water to the Red Starfish unit and it will help keep a balanced aquarium. Can be used with both marine and freshwater tanks.
