Chemistry Automation: Spend more time enjoying your pool and less time working on it.

Properly sanitized and balanced water is important for swimmer comfort and safety. It dramatically extends the life of the pool, materials and equipment. A typical misconception is that clear water is good water. While it’s true that good water will always be clear, clear water isn’t always good. Striking the right chemical balance when just about anything can affect the water can be a daunting task. Wind, rain, sun and swimmers themselves all affect water quality and balance.

Sense and Dispense, Chemistry Automation

This professional-grade ORP and pH Sense and Dispense technology was previously only available for commercial pools. Hayward now offers an economical approach, with the same level of accuracy, for residential pools. Unlike others on the market, Sense and Dispense uses a proportional feed algorithm that continuously tests the water, sampling pH and sanitizer activity, and adjusting chemical feeding on a basis proportional to the demand. Other approaches don’t sample the water often enough and release larger doses, which is far less effective and can create highs and lows similar to a manual approach.

Adding Sense and Dispense to your Pro Logic®, Aqua Plus® or Aqua Rite® Pro is a fully integrated solution – not an additional box that resides on your pool pad – eliminating additional installation costs. It also provides a single source for status reporting and control.

Sense and Dispense consists of two kits. The first kit senses pH and ORP levels and dispenses a self-renewing supply of pure chlorine generated from salt. pH dispense can be achieved using the second kit, which includes a manifold that connects to a CO2 tank. CO2 is highly effective in lowering pH. With salt-chlorinated pools, pH tends to drift up. CO2 reduces pH to recommended levels by forming H2CO3 (carbonic acid), a safe acid that does not require handling. As an alternative to CO2, Sense and Dispense also supports the Stenner Pump acid feed system – a proven solution and approach to chemical delivery. It’s robust, safe and reliable.

Commercial-Grade Sensors: Unlike laboratory-rated sensors, commercial-grade sensors are rugged and rated for large, high-demand commercial pools and outdoor conditions. Sense and Dispense® uses only commercial-grade sensors.


Adding the Sense and Dispense® option to your Pro Logic® System requires an optional salt-chlorination kit.

ProLogic or Aqua Logic revision 3.00 or higher, AquaRite Pro revision 1.00 or higher.
