Carbon is essential for bacteria and microscopic organisms to assimilate nitrogen and phosphorus, which are often present in excess in aquariums with increased filtration efficiency. Z-Carbo Plus helps to ensure that biological filtration remains efficient, reducing levels of harmful nutrients like nitrate (NO3) and phosphate (PO4).\u003c\/p\u003e\n\u003cp data-start=\"666\" data-end=\"1158\"\u003eThis natural source of biologically safe carbon replaces traditional methods like ethanol or vodka, offering a safer alternative for aquarium filtration. By promoting microbial growth and reproduction, Z-Carbo Plus enables bacteria to consume excess nitrates and phosphates, which are then exported via mechanical filtration or used as food for other organisms such as corals, clams, and sponges. Start dosing with 1ml per 100L and gradually increase as needed for optimal nutrient reduction.\u003c\/p\u003e\n\u003cp data-start=\"1160\" data-end=\"1177\"\u003e\u003cstrong data-start=\"1160\" data-end=\"1177\"\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1178\" data-end=\"1692\"\u003e\n\u003cli data-start=\"1178\" data-end=\"1284\"\u003eEnhances biological filtration by providing carbon for bacterial assimilation of nitrogen and phosphorus\u003c\/li\u003e\n\u003cli data-start=\"1285\" data-end=\"1350\"\u003eImproves the efficiency of low and ultra-low nutrient aquariums\u003c\/li\u003e\n\u003cli data-start=\"1351\" data-end=\"1430\"\u003ePromotes microbial growth and reproduction, helping reduce NO3 and PO4 levels\u003c\/li\u003e\n\u003cli data-start=\"1431\" data-end=\"1492\"\u003eBiologically safe carbon source, replacing ethanol or vodka\u003c\/li\u003e\n\u003cli data-start=\"1493\" data-end=\"1581\"\u003eIdeal for systems with low nutrients where biological filtration efficiency is reduced\u003c\/li\u003e\n\u003cli data-start=\"1582\" data-end=\"1656\"\u003eStart with 1ml per 100L and adjust based on nitrate and phosphate levels\u003c\/li\u003e\n\u003cli data-start=\"1657\" data-end=\"1692\"\u003e250ml bottle for long-lasting use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1694\" data-end=\"1954\"\u003eReef Zlements Z-Carbo Plus 250ml is a safe and effective carbon supplement for enhancing biological filtration in aquariums.
