Zodiac Filter Cleaner 1kg – Pool and Spa Chemical

Deep Cleaning for Pool and Spa Filters

Zodiac Filter Cleaner is a concentrated alkaline-salt powder designed to chemically clean cartridge, sand, glass and D.E. pool and spa filters. It breaks down oils, scale, metals and stubborn debris that can become trapped within cartridge folds or filter media.

Routine hosing and backwashing remove loose or visible dirt, but internal buildup can remain and restrict water flow. By loosening these deeper contaminants, Zodiac Filter Cleaner helps improve filtration efficiency, support clearer water and reduce unnecessary strain on the circulation system.

Features & Benefits

• Deep chemical cleaning: Cleans vital and hidden filter areas where oils, scale, metals and stubborn debris can accumulate.
• Supports stronger water flow: Helps remove restrictions that can reduce circulation through the filtration system.
• Improves filtration efficiency: Supports more effective removal of contaminants and better overall water clarity.
• Helps extend filter life: Regular chemical cleaning supports the ongoing condition of cartridge elements and sand or glass media.
• Suitable for major filter types: Designed for cartridge, sand, glass and D.E. filters used in pools and spas.
• Useful after pool treatments: Helps remove algae spores, metals and residues trapped inside the filter after algae, metal, phosphate or flocculant treatments.

How to Use

Cartridge Filters

1. Turn off the filtration system, remove the cartridge and rinse away loose dirt with clean water.
2. Dilute 500g of Zodiac Filter Cleaner in 10 litres of water using a suitable plastic container.
3. Place the cartridge in the diluted solution.
4. For best results, allow the cartridge to soak for 24 hours.
5. Remove the cartridge and rinse it thoroughly before reinstalling it.

Sand and Glass Media Filters

1. Dilute 500g of Zodiac Filter Cleaner in 10 litres of water.
2. Add the diluted solution slowly through the skimmer with the pump running.
3. Let the pump run only long enough, approximately 5–15 seconds, to draw the solution into the filter, then turn the pump off immediately.
4. Allow the filter media to soak for 24 hours for best results.
5. Clearly mark the multi-port valve or controls so the system is not accidentally restarted during the soaking period.
6. Backwash thoroughly until the discharged water runs clear, then rinse and return the system to normal filtration.

Important Usage Information

A chemical filter clean is recommended approximately every 6 months, or more frequently during periods of heavy pool use, reduced filter performance or after major water treatments.

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

What are the signs that a filter may need chemical cleaning?

Common signs include higher filter-pressure readings, weaker return flow, reduced suction-cleaner performance, recurring cloudy or dull water, increased chemical use or fine debris returning to the pool.

What is channeling in a sand filter?

Channeling occurs when oils, scale and debris cause the sand to clump or form hardened areas. Water then follows narrow paths through the media instead of filtering evenly, which can reduce filtration efficiency and contribute to cloudy water.

Can a dirty filter increase chlorine use?

Yes. Contaminants trapped inside a dirty filter can increase chlorine demand because chlorine is consumed while reacting with this buildup. Keeping the filter clean helps the sanitiser work more effectively throughout the pool.

Can a dirty filter affect a suction pool cleaner?

Yes. A restricted filter can reduce water flow and suction, causing a suction cleaner to move slowly, stop intermittently or struggle to climb pool walls. Chemical cleaning may help restore the flow needed for normal cleaner operation.

Does Zodiac Filter Cleaner change the pool's water balance?

The cleaner is used either in a separate cartridge-soaking container or inside the filter before being thoroughly backwashed to waste. When the cleaning process is completed correctly, the solution is not returned to the pool and should not affect the water balance.
