The Deluxe Test Kit is designed for pools and spa owners that need to test their total chlorine, pH, and total alkalinity levels. As this is a process that needs to be done regularly to ensure you are receiving safe and clean water, we offer replacements for deluxe test kits at your local Boldt Pools and Spa. This test kit is the ideal for any home owner. Designed for spa and pool owners who have low bather loads and test their water between visits from a service technician or trips to their pool supplies store. Keeping a balanced and safe pool has never been easier.
