Frequently asked questions
How do I know which water maintenance system is right for me?
The choice depends on your hot tub model and local water quality. The FreshWater Salt System and IQ are ideal for automation, whilst testers and softening sponges solve specific issues. We recommend a consultation to identify the optimal solution for your spa.
Are the FreshWater Salt System and IQ compatible with any hot tub?
These systems are designed for specific hot tub models. For instance, the electrolysis cartridges are compatible with Caldera Spas and Hot Spring brands, for models manufactured after 2019. To confirm compatibility with your system, please contact the Hidrostyle team.
What do the Vanishing Act sponges and the metal pre-filter do?
The Vanishing Act and Vanishing Act XL softening sponges naturally eliminate calcium and soften hard water without chemical additives, protecting the tub components. The pre-filter attaches to a garden hose to trap metals like copper and iron, as well as organic matter, during filling.
What tests can the FreshWater testers perform?
FreshWater offers two main types of testers. The 5-way version measures pH, chlorine, alkalinity, bromine, and water hardness. Additionally, there are dedicated testers exclusively for checking the salt level in the water, which are essential for the correct operation of electrolysis systems.
