A dual head pump is two peristaltic pumps that use a single motor and shaft. This is great because they always spin at the same speed and you don't have to worry about the pumps losing calibration because if they speed up or slow down they will speed up or slow down equally.
One of the pumps draws water from your saltwater container and pumps it into the tank and one pump draws water from the aquarium and pumps it down the drain. Once the lines are run any time the pump is turned on it starts changing water. You then add the pump as a simple doser. Tell hydros the speed and you can create a schedule where the pump automatically changes water each day.
