How Aquarium Carbon Functions in the Filter
Water first passes through mechanical sponges to catch debris. After that stage, Aquarium Carbon absorbs smaller pollutants before the water cycles back. This placement prevents clogs and allows the carbon to last the full month. For hobbyists seeking additional filtration solutions, explore activated resins and specialty media.
Replacement Schedule for Nano Cube Activated Carbon
Replace Nano Cube Activated Carbon every 30 days. If the water turns yellow sooner or a musty odor develops, change it immediately. Following this schedule maintains steady water quality and helps reduce stress on livestock.
