Frequently Asked Questions

What type of controller is the Dulcomarin?

The Dulcomarin controller is designed exclusively for swimming pools. The basic unit has 2 measuring inputs for measuring and controlling pH and chlorine or pH and redox potential. Two ProMinent pumps such as betas or gammas can be connected to the Dulcomarin to add chemicals for a maintenance free pool.
