# Rule Your Pool Rule Your Pool is a podcast by Orenda Technologies. This show was created for pool owners, operators, and service pros who want the best water quality possible. If you want to know what's really going on with your swimming pool chemistry, this might be the podcast for you. Each week, we'll cover a new topic related to swimming pools, water chemistry, or indoor air quality. With our help, you'll be able to rule your pool without over-treating it with chemicals and wasting money.
