Pond Ammonia Remover Filter Pouch provides fast, effective removal of toxic ammonia, nitrite, and heavy metals from pond water using natural zeolite mineral media. Simply place the pouch in your pond filter or directly in the pond to rapidly improve water quality, protect koi and goldfish from ammonia spikes, and maintain a healthy aquatic environment. Fully rechargeable for long-term use.
The Danger of Ammonia in Your Pond
Ammonia is the number one silent killer in garden ponds. 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.
How Zeolite Filter Pouches Work
Zeolite 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.
Key Features
-
Removes ammonia and nitrite — tackles the most dangerous pond pollutants
-
Heavy metal absorption — protects fish from copper, lead, zinc contamination
-
Fits most pond filters — place in any filter chamber or directly in the pond
-
Fully rechargeable — soak in salt water to regenerate and reuse
-
Natural zeolite mineral — safe for koi, goldfish, and all pond fish
-
Ideal for new ponds — critical support during filter maturation (new pond syndrome)
-
Emergency ammonia treatment — fast-acting solution for ammonia spikes
How to Use
Place 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.

When to Use Ammonia Remover Pouches
-
New pond setup: Essential during the first 6–8 weeks while filter matures
-
Ammonia emergency: Fast response when test shows elevated ammonia
-
Overstocking events: When fish numbers temporarily exceed filter capacity
-
After medication: Medications can kill beneficial bacteria — use pouch as backup
-
Hot weather: Warmer water holds less oxygen and ammonia becomes more toxic
Frequently Asked Questions
How often should I change the zeolite pouch?
Typically 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.
Can I use this in a salt water pond?
No. 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.
Does zeolite affect beneficial bacteria?
No — 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.
How many pouches do I need for my pond?
As 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.
Can I use zeolite pouches alongside my existing filter media?
Yes, 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.
