When you're fighting an algae problem fueled by high phosphate (often from tap water or heavy feeding), Phos-Zorb removes it at the source, taking away one of algae's main food supplies.\u003c\/p\u003e\u003cp style=\"font-family:Georgia,serif;font-size:1.05em;line-height:1.8;margin:0 0 16px;background-color:#fbeee0;border:1px solid #e6b98a;padding:14px 18px;color:#7a3d0c;\"\u003e\u003cstrong\u003eA Gentle Word of Caution — mind your plants:\u003c\/strong\u003e Phosphate is also an essential \u003cem\u003eplant nutrient\u003c\/em\u003e, so in a planted aquascape, aggressively stripping it out with Phos-Zorb can cause phosphorus-deficiency in your plants (stunted, dark, pinholed growth). In a planted tank the goal is usually to \u003cem\u003ebalance\u003c\/em\u003e phosphate, not eliminate it. Phos-Zorb is most appropriate for fish-only tanks with an algae problem; in a planted tank, use it cautiously and watch your plants.\u003c\/p\u003e\u003cp style=\"font-family:Georgia,serif;font-size:1.05em;line-height:1.8;margin:0 0 16px;color:#2c2c2c;\"\u003e\u003cstrong\u003eGood to Know:\u003c\/strong\u003e Phos-Zorb is distinct from the nitrogen-removing Nitra-Zorb and the general-purpose Bio-Chem Zorb — it's the phosphate\/silicate specialist. A phosphate test kit helps you confirm a high reading before using it and avoid overshooting.\u003c\/p\u003e\u003cp style=\"font-family:Georgia,serif;font-size:1.05em;line-height:1.8;margin:0;color:#2c2c2c;\"\u003e\u003cstrong\u003eHow to Use:\u003c\/strong\u003e Rinse and place in the filter's flow path after mechanical media. Replace when it stops lowering your phosphate readings; pair it with the underlying fixes (less feeding, more water changes) for lasting algae control.\u003c\/p\u003e","brand":"Central","offers":[{"title":"Default Title","offer_id":48498158666039,"sku":"317163011096","price":8.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/8748\/1655\/files\/central-filter-accessories-default-title-api-phos-zorb-filter-media-41608068759863.jpg?v=1778253218","url":"https:\/\/cuboidstore.com\/products\/api-phos-zorb-filter-media","provider":"Cuboid Aquatics LLC","version":"1.0","type":"link"}
