It is sold by weight in six sizes, from a 200g top-up to a 10kg bulk bag, so you can buy exactly the amount your filter chamber holds. Zeolite can be recharged for repeat use.\u003c\/p\u003e\n\n\u003ch2\u003eThe Danger of Ammonia in Your Pond\u003c\/h2\u003e\n\u003cp\u003eAmmonia is the number one silent killer in garden ponds. It is 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. In newly set up ponds, during overstocking, or after any disruption to your filter bacteria, ammonia can rise to dangerous levels within hours.\u003c\/p\u003e\n\n\u003ch2\u003eWhy It Works\u003c\/h2\u003e\n\u003ch3\u003eIon exchange physically removes ammonia\u003c\/h3\u003e\n\u003cp\u003eZeolite is a naturally occurring mineral with a highly porous, negatively charged crystal structure. That structure attracts and holds positively charged ammonium ions through ion exchange, physically removing ammonia from the water rather than just converting it. The ammonia stays locked in the stone until you recharge or replace it.\u003c\/p\u003e\n\u003ch3\u003eFinely granulated for a larger working surface\u003c\/h3\u003e\n\u003cp\u003eThis zeolite is crushed into fine angular granules. Smaller pieces expose more surface to the water than large lumps, so the media reduces ammonia levels more quickly. The trade-off is that fine granules must be contained: use a media bag or a tray with small openings so they cannot wash into your pump.\u003c\/p\u003e\n\u003ch3\u003eIt supports, not replaces, your biological filter\u003c\/h3\u003e\n\u003cp\u003eZeolite does not harm the nitrifying bacteria in your filter. It takes some of the ammonia load off them, which matters most while a new filter is maturing.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRemoves ammonia, the most dangerous pond pollutant\u003c\/li\u003e\n\u003cli\u003eFits most pond filters, in a media bag or media tray\u003c\/li\u003e\n\u003cli\u003eRechargeable in salt water for repeat use\u003c\/li\u003e\n\u003cli\u003eNatural zeolite mineral, safe for koi, goldfish and all pond fish\u003c\/li\u003e\n\u003cli\u003eIdeal for new ponds during filter maturation (new pond syndrome)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhere It's Used\u003c\/h2\u003e\n\u003cp\u003eUse it in box filters, gravity multi-chamber filters, filter trays under waterfalls and skimmer baskets, and in pond-side quarantine or hospital tanks.

Fill a media bag or tray to the depth your filter chamber allows, leaving room for water to flow through and around it. As a rough guide, 200g and 600g suit aquariums, small patio ponds and compact filters; 1kg and 2kg fill a media bag in a typical garden-pond box filter; 5kg suits larger box and multi-chamber filters or two bags used in rotation; and 10kg is the economical choice for koi ponds, several filters or keeping a recharge stock. To rotate media, buy enough for two loads so one can recharge while the other works.\u003c\/p\u003e\n\n\u003ch2\u003eHow to Use and Care for It\u003c\/h2\u003e\n\u003cp\u003eRinse the zeolite before use to remove dust. Place it in a mesh media bag in your filter's media chamber, in the skimmer basket, or in a media tray where water flows through it; for pond filters, a fine-mesh drawstring filter bag holds the granules best. Replace or recharge every 4–8 weeks depending on stocking and water quality. To recharge, rinse the bag and soak it in a strong salt solution (25g salt per litre of water) for 24 hours, then rinse thoroughly with fresh water before returning it to the filter.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eHow often should I change the zeolite?\u003c\/strong\u003e\u003cbr\u003eTypically every 4–8 weeks under normal stocking. In heavily stocked ponds or during summer you may need to recharge or replace it more often. Test weekly; if ammonia rises above 0.25mg\/L, recharge or replace it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this in a salted pond?\u003c\/strong\u003e\u003cbr\u003eNo. Zeolite releases ammonia back into the water in the presence of salt, which is why salt is used for recharging. Do not use it in ponds treated with pond salt above 1g\/L.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes zeolite remove nitrite?\u003c\/strong\u003e\u003cbr\u003eNo. Zeolite works on ammonia. Nitrite is handled by your biological filter, so keep that healthy and test for nitrite separately.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use zeolite alongside my existing filter media?\u003c\/strong\u003e\u003cbr\u003eYes. Zeolite works well alongside biological and mechanical media. It is not a replacement for a proper filter, but an important supplement during cycling, emergencies and periods of high stocking.\u003c\/p\u003e\n\n\u003ch2\u003eOrdering and Delivery\u003c\/h2\u003e\n\u003cp\u003eChoose your weight from the options above; every size is the same finely granulated natural zeolite.
