Burtons Auto Top-Up Marine Amino & Vitamins but it may also dropThe Burtons Auto Top up system is designed to keep a constant water level in you pond. When the water level of your pond drops below the low sensor the unit open the mains water solenoid letting water though to top up the pond. Once the water has reached the high level sensor the unit shuts the solenoid off again stopping the water flow. With all ponds keeping a constant water level is important and more so for systems with a gravity fed drum filter.
