Hot Tub Things® Spa Clarifier - Clears Cloudy Spa Water (16 fl oz & 32 fl oz)

Q: Will this clarifier work with my saltwater spa system?

A: Yes — the formula is safe and compatible with chlorine, bromine, salt, ozone and mineral sanitation systems.

Q: How often should I use it?

A: Use when water appears cloudy or after heavy use; you can also use it periodically (e.g., monthly) to improve filtration efficiency.

Q: Does it affect pH, alkalinity or sanitizer levels?

A: No — this product is designed to clarify water and enhance filtration; it does not significantly change pH or sanitizer residual when used as directed.

Q: Can I use pool clarifier instead of spa clarifier?

A: It’s not recommended — spa-specific products are formulated for smaller water volumes and higher temperatures, ensuring safer and more effective results. Reddit+1

Q: Which size should I buy?

A: The 16 fl oz size is sufficient for typical spa volumes and moderate use; the 32 fl oz variant is better suited for larger spas, higher bather loads or more frequent use.

Test and confirm that sanitizer, pH and alkalinity levels are within the recommended range.

With the circulation system running, add the recommended dose of Spa Clarifier to the water (refer to label for gallons to oz ratio).

Continue jets/circulation for at least 15 minutes to allow the flocculant to bind particles and send them to the filter.

After circulation, clean or rinse your filter cartridge to remove the aggregated particles.

Retest clarity and water parameters before spa use.

Store the product in a cool, dry place, tightly sealed and away from direct sunlight.
