Natural Clarity Care for Cleaner, Brighter Pool Water
Zodiac Natural Clarifier is a chitosan-based liquid treatment for pool water that looks cloudy, dull or affected by oils and waterline scum. It helps restore a cleaner, brighter pool appearance while supporting more effective removal of fine suspended material.
Made with naturally derived chitosan from reclaimed crustacean shells, the formula brings tiny particles together into larger groups that are easier for the pool filter to collect. It also helps manage oils, grease, scum marks and metals in the water.
Features & Benefits
- Clears cloudy pool water: Helps remove fine suspended material responsible for a dull or hazy appearance.
- Natural chitosan formula: Uses a naturally derived clarifying ingredient made from reclaimed crustacean shells.
- Improves filtration efficiency: Makes small particles easier for the pool filter to capture and remove.
- Helps reduce oils and scum marks: Supports cleaner water and a tidier appearance around the pool waterline.
- Helps remove metals: Provides additional support for reducing metal contamination in pool water.

How to Use
- Measure the required dose according to the pool volume and application.
- Dilute the product in a clean container of pool water.
- Apply the diluted treatment evenly around the edges of the pool.
- Run the filtration system for at least 6 hours to allow the filter to collect the grouped particles.
- After treatment, backwash the media filter or rinse the cartridge element if required to remove the additional collected debris.
Dosage & Coverage
- Cloudy pool water: Add 60mL per 10,000 litres of pool water.
- Weekly maintenance: Add 30mL per 10,000 litres of pool water.
- Heavy bather load: Add an additional dose following pool parties or periods of high pool use.
Important Usage Information
- Do not exceed the recommended dose. Too much liquid clarifier can interfere with particle grouping and make the water appear cloudier.
- If the first treatment does not achieve the desired clarity, wait approximately one week before applying another dose.
- Use Natural Clarifier for mild cloudiness and ongoing clarity care. Treat active algae, low sanitiser levels or poor water balance separately.
- Do not mix directly with other pool chemicals. Add each product separately.
Maintain free chlorine at 2–4ppm and pH at 7.2–7.6. Keep Total Alkalinity at 80–120ppm for fully tiled, pebble and plaster pools, or 125–150ppm for vinyl and fibreglass pools.
A Better Pool Experience Starts with the Right Chemistry
Zodiac pool chemicals support the key parts of everyday water care, from balance and sanitising to algae prevention, clarity, stain control and equipment protection.
Each product has a clear role in helping pool water stay cleaner, more comfortable and easier to manage, so the pool feels ready to enjoy more often.

Frequently Asked Questions
How is Zodiac Natural Clarifier different from standard Zodiac Clarifier?
Zodiac Natural Clarifier uses naturally derived chitosan and provides additional support for oils, grease, waterline scum and metals. Standard Zodiac Clarifier uses a cationic polyelectrolyte and is focused primarily on clearing cloudy water and improving filtration efficiency.
Can Zodiac Natural Clarifier be used with different filter types?
Yes. As a liquid clarifier, it can be used with cartridge, sand and glass-media filtration systems. Clean or backwash the filter after treatment if it has collected a significant amount of additional debris.
How does chitosan help with water clarity, oils and scum marks?
Chitosan attracts fine suspended particles, oils and grease, bringing them together into larger groups that are easier for the pool filter to capture. This helps improve water clarity and reduce the buildup that contributes to scum marks around the waterline.
Why should the filter run for at least 6 hours?
The clarifier groups fine suspended material together, but the filtration system must then collect it. Running the filter for at least 6 hours gives the treated particles time to circulate through the system and be removed from the water.
Can Zodiac Natural Clarifier be used after algae treatment?
Yes. Once the algae has been controlled, Natural Clarifier can help the filter collect fine dead material that remains suspended and leaves the pool water looking cloudy.
What is the difference between a clarifier and a flocculant?
A clarifier groups fine particles for collection by the pool filter while normal circulation continues. A flocculant forms heavier clumps that settle onto the pool floor and must then be vacuumed to waste.
