It's suited to new ponds settling in and to regular water changes where the source water runs soft, and it tops up the minerals that soft water lacks.\u003c\/p\u003e\u003cp\u003eOase AquaActiv OptiPond is a mineral-based conditioner made specifically for ponds filled with rainwater or well water, water sources that naturally run low in hardness and trace elements, and it helps protect fish from the swings in pH that this soft water can cause. That focus is what separates it from a general all-purpose conditioner: it's built to correct a particular water type rather than treat everything at once.\u003c\/p\u003e\u003cp\u003eIt's suitable for ponds being filled or topped up from these softer sources, including new ponds settling in and ongoing water changes. The formula helps stabilise carbonate and total hardness, which in turn keeps pH from dropping suddenly, a swing that can stress or injure fish.\u003c\/p\u003e\u003cp\u003eIt also binds ammonium and ammonia gas, and can help when ammonia, nitrite or heavy metal levels spike unexpectedly. Alongside that, it replenishes macro elements such as sodium, potassium, calcium and magnesium, so the water chemistry stays balanced rather than just one reading being patched.\u003c\/p\u003e\u003cp\u003eWhat you get is a single container of OptiPond, supplied as either a 500 ml or 5 L bottle. Match the size to your pond's volume: the smaller bottle is intended for smaller ponds and the larger one for substantially bigger volumes, so check your figures before choosing.\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFormulation type\u003c\/td\u003e\n\u003ctd\u003eLiquid pond water stabiliser\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAvailable sizes\u003c\/td\u003e\n\u003ctd\u003e500 ml; 5 L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePond suitability (500 ml)\u003c\/td\u003e\n\u003ctd\u003ePonds up to 5 m³\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePond suitability (5 L)\u003c\/td\u003e\n\u003ctd\u003ePonds up to 50 m³\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCarbonate hardness increase (at recommended dose)\u003c\/td\u003e\n\u003ctd\u003e+1.5 °dKH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal hardness increase (at recommended dose)\u003c\/td\u003e\n\u003ctd\u003e+1.9 °dH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"AquaticsHub","offers":[{"title":"500ml","offer_id":57621372862837,"sku":null,"price":17.99,"currency_code":"GBP","in_stock":true},{"title":"5L","offer_id":57621372895605,"sku":null,"price":172.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/0610\/4949\/files\/500ml.png?v=1790923288","url":"https:\/\/aquaticshub.co.uk\/products\/oase-aquaactiv-optipond-pond-water-stabiliser","provider":"AquaticsHub","version":"1.0","type":"link"}
