Product Questions

The controller mentions a float switch. Is that something that comes with this, or that one can purchase separately to add on?
Question by: Eli on Aug 14, 2022, 12:33 PM
Thanks for the question! ReefBreeders has a goal of being able to add a float switch as an optional accessory in the future to allow the pump to turn off at a high or low water level, this is still in the works but they have the controller all set up for it for when this does come to fruition. Please let us know if we can help with anything else!
