This pure, non-iodised aquatic salt reduces fish stress, aids recovery from disease and injury, improves gill function, and helps maintain electrolyte balance in pond water. Safe for koi, goldfish, and most pond plants when used at correct dosages.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch2\u003eWhy Every Koi Keeper Should Use Pond Salt\u003c\/h2\u003e\n\u003cp\u003eSalt has been used in fishkeeping for centuries, and for good reason — it works. In a pond environment, a low-level salt solution (0.1–0.3% concentration) creates an \u003cstrong\u003eosmotic advantage\u003c\/strong\u003e for fish, reducing the energy they must spend on osmoregulation (maintaining the right balance of water and salts in their bodies). This freed energy goes directly toward immune function, healing, and growth.\u003c\/p\u003e\n\n\u003ch3\u003ePure Aquatic Grade: No Additives, No Iodine\u003c\/h3\u003e\n\u003cp\u003eCritically, not all salt is equal.

Our pond salt is \u003cstrong\u003e100% pure sodium chloride\u003c\/strong\u003e, mined from natural deposits and processed to aquatic-grade purity.

Avoid high concentrations (above 0.3%) for extended periods. Some sensitive aquatic plants may be less tolerant — research your specific plants before treating.\u003c\/p\u003e\n\n\u003ch3\u003eDoes pond salt evaporate or need topping up?\u003c\/h3\u003e\n\u003cp\u003eSalt does not evaporate — only water evaporates. When you top up your pond after evaporation loss, you don't need to add more salt. Only replace salt after a significant water change that dilutes the existing concentration.\u003c\/p\u003e\n\n\u003ch3\u003eWill pond salt affect my biological filter?\u003c\/h3\u003e\n\u003cp\u003eAt maintenance concentrations (0.1%), salt has minimal effect on beneficial bacteria. At treatment concentrations (0.2–0.3%), some bacterial activity may slow temporarily. Maintain excellent filtration and aeration during any salt treatment.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use table salt instead of pond salt?\u003c\/h3\u003e\n\u003cp\u003eNo — never use table salt in a pond. Table salt contains iodine (toxic to fish) and anti-caking agents that can harm beneficial bacteria and pond life. Always use purpose-made aquatic pond salt.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I measure salt concentration in my pond?\u003c\/h3\u003e\n\u003cp\u003eUse a salt refractometer or aquatic salinity test kit. These give accurate percentage readings so you can maintain safe, effective concentrations.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003e🚚 Free UK delivery | 📦 Dispatched within 1 business day | 💬 Expert pond advice available\u003c\/em\u003e\u003c\/p\u003e","brand":"PondLiners Co","offers":[{"title":"1kg","offer_id":57667259662684,"sku":null,"price":45.0,"currency_code":"GBP","in_stock":true},{"title":"2.5kg","offer_id":57667259695452,"sku":null,"price":89.97,"currency_code":"GBP","in_stock":true},{"title":"5kg","offer_id":57667259728220,"sku":null,"price":149.97,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0889\/2035\/9260\/files\/d2b72f244628cc235d8d15d10ad0a4f3.jpg?v=1779042658","url":"https:\/\/www.pondlinersco.co.uk\/products\/pond-salt-uk-pure-aquatic-salt-for-koi-goldfish-reduces-stress-aids-recovery","provider":"PondLinersco.co.uk","version":"1.0","type":"link"}
