It's produced continuously by fish waste, uneaten food, and decaying plant matter. Even at low concentrations, ammonia damages fish gills, suppresses immunity, and causes chronic stress. Nitrite — the product of ammonia oxidation — is equally toxic. In newly set up ponds, during overstocking events, or after any disruption to your filter bacteria, ammonia can spike to dangerous levels within hours.\u003c\/p\u003e\n\n\u003ch2\u003eHow Zeolite Filter Pouches Work\u003c\/h2\u003e\n\u003cp\u003eZeolite is a naturally occurring mineral with a highly porous, negatively charged crystal structure. This structure attracts and traps positively charged ammonia ions through a process called ion exchange — physically removing ammonia from the water rather than just converting it. Heavy metals including copper, lead, and zinc are also bound by the zeolite matrix, providing additional protection for your fish.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemoves ammonia and nitrite\u003c\/strong\u003e — tackles the most dangerous pond pollutants\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy metal absorption\u003c\/strong\u003e — protects fish from copper, lead, zinc contamination\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits most pond filters\u003c\/strong\u003e — place in any filter chamber or directly in the pond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully rechargeable\u003c\/strong\u003e — soak in salt water to regenerate and reuse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNatural zeolite mineral\u003c\/strong\u003e — safe for koi, goldfish, and all pond fish\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIdeal for new ponds\u003c\/strong\u003e — critical support during filter maturation (new pond syndrome)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmergency ammonia treatment\u003c\/strong\u003e — fast-acting solution for ammonia spikes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHow to Use\u003c\/h2\u003e\n\u003cp\u003ePlace the pouch in your pond filter media chamber, in the pond skimmer basket, or suspend directly in the pond water. The zeolite works best with good water flow through it. Replace or recharge every 4–8 weeks depending on stocking levels and water quality. To recharge: rinse the pouch and soak in a strong salt solution (25g salt per litre of water) for 24 hours, then rinse thoroughly with fresh water before returning to the pond.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003ctable class=\"specs-table\" style=\"width:100%;border-collapse:collapse;\"\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003cth style=\"padding:8px;border:1px solid #ddd;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:8px;border:1px solid #ddd;text-align:left;\"\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eMedia Type\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eNatural zeolite mineral\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003ePack Options\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eSingle, Twin Pack, 4-Pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eRemoves\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eAmmonia, nitrite, heavy metals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eRechargeable\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eYes — salt water soak\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003ePlacement\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eFilter chamber, skimmer, or pond\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eSuitable For\u003c\/td\u003e\n\u003ctd style=\"padding:8px;border:1px solid #ddd;\"\u003eKoi, goldfish, all pond fish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhen to Use Ammonia Remover Pouches\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew pond setup:\u003c\/strong\u003e Essential during the first 6–8 weeks while filter matures\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmmonia emergency:\u003c\/strong\u003e Fast response when test shows elevated ammonia\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverstocking events:\u003c\/strong\u003e When fish numbers temporarily exceed filter capacity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAfter medication:\u003c\/strong\u003e Medications can kill beneficial bacteria — use pouch as backup\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHot weather:\u003c\/strong\u003e Warmer water holds less oxygen and ammonia becomes more toxic\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eHow often should I change the zeolite pouch?\u003c\/h3\u003e\n\u003cp\u003eTypically every 4–8 weeks under normal stocking conditions. In heavily stocked ponds or during summer, you may need to recharge or replace more frequently. Test your water weekly with an ammonia test kit — if ammonia rises above 0.25mg\/L, recharge or replace the pouch.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use this in a salt water pond?\u003c\/h3\u003e\n\u003cp\u003eNo. Zeolite releases ammonia back into the water in the presence of salt, which is why salt is used for recharging. Do not use zeolite pouches in ponds treated with pond salt at levels above 1g\/L, as this will cause the zeolite to release rather than absorb ammonia.\u003c\/p\u003e\n\n\u003ch3\u003eDoes zeolite affect beneficial bacteria?\u003c\/h3\u003e\n\u003cp\u003eNo — zeolite does not harm the nitrifying bacteria in your filter. It provides complementary protection by directly absorbing ammonia from the water, reducing the load on your biological filter and protecting fish during filter maturation.\u003c\/p\u003e\n\n\u003ch3\u003eHow many pouches do I need for my pond?\u003c\/h3\u003e\n\u003cp\u003eAs a guide, use one standard pouch per 500–1000 litres of pond water. For heavily stocked koi ponds, use the 4-Pack and rotate pouches on a recharge schedule so you always have active media in the pond.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use zeolite pouches alongside my existing filter media?\u003c\/h3\u003e\n\u003cp\u003eYes, zeolite works excellently alongside biological and mechanical filter media. It's not a replacement for a proper filter but an important supplementary treatment, especially during cycling, emergencies, and high stocking periods.\u003c\/p\u003e\n\n\u003c\/div\u003e","brand":"PondLiners Co","offers":[{"title":"Single Pouch","offer_id":57667522888028,"sku":null,"price":33.0,"currency_code":"GBP","in_stock":true},{"title":"Twin Pack","offer_id":57667522920796,"sku":null,"price":59.97,"currency_code":"GBP","in_stock":true},{"title":"4-Pack","offer_id":57667522953564,"sku":null,"price":107.97,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0889\/2035\/9260\/files\/a4ba2b2b578f5bb797a337d0db6da53e.jpg?v=1779047582","url":"https:\/\/www.pondlinersco.co.uk\/products\/pond-ammonia-remover-filter-pouch-uk-removes-nitrite-heavy-metals-koi-safe","provider":"PondLinersco.co.uk","version":"1.0","type":"link"}
