Carbon is essential for bacteria and microscopic organisms to assimilate nitrogen and phosphorus, helping to prevent nutrient pollutants like nitrate (NO3) and phosphate (PO4) from accumulating in your tank.\u003c\/p\u003e\n\u003cp data-start=\"525\" data-end=\"1021\"\u003eZ-Carbo Plus enhances microbial growth, enabling plankton and bacteria to consume excess nitrates and phosphates. These beneficial bacteria are then exported via mechanical filtration or used as food for other organisms such as corals, clams, and sponges. This biologically safe carbon supplement replaces flammable alternatives like ethanol or vodka, ensuring a safer solution for your aquarium. Start with 1ml per 100L, and gradually increase the dosage until nutrient levels are close to 0ppm.\u003c\/p\u003e\n\u003cp data-start=\"1023\" data-end=\"1040\"\u003e\u003cstrong data-start=\"1023\" data-end=\"1040\"\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1041\" data-end=\"1581\"\u003e\n\u003cli data-start=\"1041\" data-end=\"1123\"\u003eProvides carbon for enhanced microbial growth and improved biological filtration\u003c\/li\u003e\n\u003cli data-start=\"1124\" data-end=\"1194\"\u003eHelps reduce excess nutrients like nitrate (NO3) and phosphate (PO4)\u003c\/li\u003e\n\u003cli data-start=\"1195\" data-end=\"1256\"\u003eBiologically safe carbon source, replacing ethanol or vodka\u003c\/li\u003e\n\u003cli data-start=\"1257\" data-end=\"1344\"\u003eImproves the efficiency of filtration systems in low and ultra-low nutrient aquariums\u003c\/li\u003e\n\u003cli data-start=\"1345\" data-end=\"1426\"\u003ePromotes healthy coral, clams, and sponges by supporting microbial food sources\u003c\/li\u003e\n\u003cli data-start=\"1427\" data-end=\"1520\"\u003eStart with 1ml per 100L and adjust up to 3ml per 100L based on nitrate and phosphate levels\u003c\/li\u003e\n\u003cli data-start=\"1521\" data-end=\"1581\"\u003e500ml bottle for long-lasting use and effective filtration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1583\" data-end=\"1910\"\u003eReef Zlements Z-Carbo Plus 500ml is a carbon supplement that enhances biological filtration by providing essential carbon for bacteria to consume excess nitrates and phosphates.
