The MarineDepot.com staff demonstrates how an aquarium top-off system senses when your water level drops and replenishes water automatically. No more lugging buckets of water or arranging someone to come by and fill up the tank while you're away! Automatic top-off systems contribute to a healthier tank, too: saltwater systems maintain constant salinity and protein skimmers function more steadily.
