This document provides an overview of spa care compared to pool care. It discusses that while spas are smaller than pools, they require different care due to features like jets and covers. The six keys to proper spa care are circulation, filtration, cleaning, draining and refilling, testing, and chemicals. Circulation is important for spa care as spas have higher turnover rates than pools. Filtration and cleaning are also important due to the higher water temperatures in spas. Proper testing and maintenance of chemical levels like pH and sanitizer are necessary. Draining and refilling frequency depends on usage, with heavier used spas needing more frequent draining.
