Product Overview

What pool techs reach for when organic scum and bather oils create cloudy water lines without throwing off water balance.

Sirona Natural Clear Enzyme Clarifier comes in a 16 fl oz bottle powered by natural enzymes to break down non-living organics, oils, and lotions. Unlike traditional polymer coagulants that load up filter media, this biodegradable and phosphate-free formula digests surface scum while remaining fully compatible with chlorine, bromine, and mineral sanitizers.

Why Pool Pros Trust This

Benefits & What Makes It Different

Natural Enzyme Digestion

Breaks down sunscreen, cosmetics, and body oils organically to eliminate water line scum without clogging filter cartridges.

Phosphate-Free Chemistry

Delivers crisp water clarity without adding unwanted nutrients that can feed biological growth in warm water.

Broad Sanitizer Compatibility

Formulated to perform reliably alongside chlorine, bromine, biguanide, and saltwater systems without disrupting pH or alkalinity.

Product Details

Active Ingredient

Natural Broad-Spectrum Enzyme Blend (Proprietary Clarifier)

Recommended Dosing

1 fl oz per 500 gal weekly for spas; 16 fl oz per 10,000 gal for pool maintenance

Compatibility

  • Compatible with chlorine, bromine, biguanide, ozone, and saltwater sanitizers
  • Safe for all surfaces including vinyl, fiberglass, plaster, and acrylic spa shells
  • Avoid dosing directly into water with sanitizer levels above 5 ppm shock

When To Use This

Preventing and breaking down waterline scum in hot tubs and spasClearing water cloudiness caused by high bather load and sunscreen accumulationExtending filter run cycles between deep chemical cleanings

Pro Tip

Apply enzyme clarifiers when free chlorine is between 1–3 ppm; dosing right after an aggressive shock (above 5 ppm) can temporarily deactivate the enzymes before they digest organic oils. In sunbelt regions where sunscreen load is continuous, weekly enzyme dosing prevents chronic filter gumming.

Common Questions & Instructions

How does Sirona Natural Clear Enzyme Clarifier differ from standard synthetic clarifiers?

While standard polymer clarifiers mechanically clump fine particles for the filter to catch, Sirona Natural Clear uses enzymes to biologically digest organic oils, lotions, and scum lines, reducing filter maintenance without adding phosphate residue.

Can I use Sirona Natural Clear in a bromine or saltwater spa?

Yes, this 16 fl oz formula is fully compatible with bromine, chlorine, mineral, and saltwater systems, operating effectively within normal water ranges such as pH 7.2–7.6 and total alkalinity 80–120 ppm.

How often should I dose Sirona Natural Clear in my spa or pool?

For routine maintenance, dose 1 fl oz per 500 gallons weekly with circulation running, or double the dose following heavy bather usage or high-heat weekends.
