**Background and Problem Statement:** Modern water filtration systems used in residential pool applications require the user to balance and maintain the chemical properties of the water within the system. Unmaintained or unbalanced water causes systems to run inefficiently, or, in extreme cases, the water can damage heating and filtration systems. To maintain and balance the water, the user must determine the water's sanitizer concentration, acidity, and alkalinity, then add the necessary chemicals if correction is needed. In residential systems, this process must be manually completed by the system user. **Vision:** This project aims to create an open-source system that automates the chemical balance for residential pools. The final product itself will be relatively low maintenance and non-invasive to the existing filtration and heating system. This will be achieved by keeping the project separate from the existing pool system so that it can be implemented in a location that is both accessible and out of the way.
