Frequently Asked Questions

What causes cloudy spa water?

Cloudy spa water is typically caused by fine suspended particles that are too small for the filter to capture on their own. Common sources include body oils, sunscreen, cosmetics, dead skin cells, calcium carbonate precipitation (from high pH or alkalinity), and organic waste from bathers. A clarifier like Zodiac Spa Natural Clarifier binds these fine particles together into larger clumps that the filter can then remove, restoring water clarity.

What is Chitosan and is it safe?

Chitosan is a natural polymer derived from chitin, which is found in the shells of crustaceans such as prawns and crabs. It is widely used as a natural flocculant and clarifier in water treatment. In spa applications, it is considered safe for bathers when used as directed. Note: if you have a shellfish allergy, consult your doctor before using chitosan-based products in your spa.

How do I use Zodiac Spa Natural Clarifier?

Add the recommended dose of Zodiac Spa Natural Clarifier directly to the spa water with the pump running. The clarifier will begin binding fine particles together for the filter to capture. Run the filter for several hours after dosing and clean or backwash the filter after treatment to remove the captured particles. Refer to the product label for specific dosing rates based on your spa volume.

Will clarifier affect my water chemistry?

Zodiac Spa Natural Clarifier is formulated to work without significantly affecting pH, alkalinity, or sanitiser levels. However, always test your water chemistry after any chemical addition and adjust as needed. If your spa water is persistently cloudy despite clarifier treatment, check your sanitiser levels, pH, and filter condition — cloudy water is often a sign of an underlying water balance or filtration issue.
