Zodiac Filter Cleaner 500g | Sand & Glass Media Pool Filter Cleaner
Backwashing removes trapped particles but leaves behind a greasy, oily film that coats the filter media over time. This biofilm reduces filtration efficiency, causes water to channel through the media rather than filter through it, and means your pump works harder for worse results. Zodiac Filter Cleaner breaks down this film chemically, something backwashing simply cannot do.
- Greasy film on filter media reduces effective filtration surface area
- Channelling allows unfiltered water to bypass the media entirely
- Reduced filtration means more chemicals needed to maintain water clarity
- Regular filter cleaning extends media life and reduces pump wear Key Features
- Removes Grease, Oils and Debris. Dissolves the biofilm backwashing leaves behind.
- Restores Filter Efficiency. Brings filter media back to near-new performance.
- Suitable for Sand and Glass Media Filters. Works with all standard pool filter media.
- Improves Water Clarity. Better filtration means cleaner, clearer water.
- Reduces Chemical Costs. Efficient filtration means chlorine and other chemicals work more effectively. How to Use
- Turn off the filter and disconnect the power
- Remove the filter cover for access to the filter housing
- Add the full 500g of Zodiac Filter Cleaner directly into the filter housing and mix where possible
- Leave for 24 hours to allow the cleaner to dissolve grease, oils, and debris
- Backwash the filter thoroughly, then run a rinse cycle for 10 seconds
- Resume normal filtration - your filter is now restored to full performance
Tip: For best results, clean your filter at the start and end of each pool season, and any time you notice reduced water flow or clarity that doesn't improve with backwashing alone. Do not swim during the 24-hour treatment period. How Often Should You Clean Your Filter?
- Minimum: Once per season (start of summer)
- Recommended: Twice per season - start and end of summer

Q: How is this different from just backwashing?
A: Backwashing flushes out trapped particles but leaves a greasy biofilm on the media. Zodiac Filter Cleaner chemically dissolves this film, restoring the media's full filtration surface, something backwashing alone cannot achieve.
Q: Is this suitable for cartridge filters?
A: No - this product is formulated for sand and glass media filters. For cartridge filters, a dedicated cartridge cleaner is recommended.
Q: Can I swim while the filter cleaner is working?
A: No - the filter is off during the 24-hour treatment period. Wait until you have completed the backwash and rinse cycle and resumed normal filtration before swimming.
Q: How do I know if my filter needs cleaning?
A: Signs include reduced water flow from return jets, cloudy water that doesn't respond to chemicals, filter pressure running consistently high, or it's been more than 6 months since your last filter clean.
Q: How long will a 500g pack last?
A: One 500g pack provides one complete treatment for a standard residential pool filter. For twice-yearly cleaning, you'll need 2 packs per season.
Q: Will this damage my filter media?
A: No - Zodiac Filter Cleaner is specifically formulated to be safe on sand and glass filter media while effectively removing grease and oil build-up.
Q: Is this product covered by a warranty?
A: Yes, this product is backed by a manufacturer warranty. For warranty queries,. Pickup and Delivery
