Carbon is essential for bacteria and microscopic organisms to assimilate nitrogen and phosphorus, making it a crucial component of efficient biological filtration. When systems are carbon-depleted, the efficiency of nutrient removal decreases, leading to an increase in pollutants like nitrate (NO3) and phosphate (PO4).\u003c\/p\u003e\n\u003cp data-start=\"647\" data-end=\"1093\"\u003eZ-Carbo Plus promotes the growth and reproduction of beneficial microbes that consume these harmful nutrients, ensuring cleaner water and healthier aquarium inhabitants. This biologically safe carbon source replaces ethanol or vodka, providing a safer and more effective solution for nutrient management. The supplement can be dosed at 1ml per 100L and increased up to 3ml per 100L as needed, helping to maintain balanced water quality over time.\u003c\/p\u003e\n\u003cp data-start=\"1095\" data-end=\"1112\"\u003e\u003cstrong data-start=\"1095\" data-end=\"1112\"\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1113\" data-end=\"1713\"\u003e\n\u003cli data-start=\"1113\" data-end=\"1216\"\u003eEnhances biological filtration by providing carbon for bacteria to assimilate nitrogen and phosphorus\u003c\/li\u003e\n\u003cli data-start=\"1217\" data-end=\"1287\"\u003eHelps reduce excess nutrients like nitrate (NO3) and phosphate (PO4)\u003c\/li\u003e\n\u003cli data-start=\"1288\" data-end=\"1367\"\u003ePromotes microbial growth and reproduction for a healthier aquarium ecosystem\u003c\/li\u003e\n\u003cli data-start=\"1368\" data-end=\"1429\"\u003eBiologically safe carbon source, replacing ethanol or vodka\u003c\/li\u003e\n\u003cli data-start=\"1430\" data-end=\"1478\"\u003eIdeal for low and ultra-low nutrient aquariums\u003c\/li\u003e\n\u003cli data-start=\"1479\" data-end=\"1546\"\u003eStart with 1ml per 100L and increase as needed up to 3ml per 100L\u003c\/li\u003e\n\u003cli data-start=\"1547\" data-end=\"1606\"\u003e5000ml bottle for long-lasting, efficient supplementation\u003c\/li\u003e\n\u003cli data-start=\"1607\" data-end=\"1713\"\u003eSupports coral, sponges, clams, and other organisms by providing a food source for plankton and bacteria\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1715\" data-end=\"2007\"\u003eReef Zlements Z-Carbo Plus 5000ml is a carbon supplement that boosts biological filtration, reduces excess nutrients, and supports a healthy reef ecosystem.
