Key benefits Clear water without black water: Activated carbon removes impurities without turning the water dark, reducing the need to constantly muddy aquarium water. Nonpowdery solid cube with a porous honeycomb: delivers clear water with minimal impurities, while its fragile nature does not affect efficient use. Easy and neat placement: 3D shape and unique configuration allow tidy installation in any aquarium without carbon powder shedding. Effective filtration performance: the honeycomb structure adsorbs pollutants, impurities, and turbid matter to promote crystalclear water and a healthier habitat. Maintenance guidance for results: place near the fish tank water pump inlet to prevent blockage; rinse or every 36 months to maintain filtering performance. Do not place the grid filter downward. What it is and how it works Material: Activated carbon Form: Solid cube Structure: Porous honeycomb with a threedimensional shape for efficient adsorption Design notes: Nonpowdery, solid cube that provides reliable filtration; the cube is relatively fragile yet does not compromise performance How to use Placement: Install near the fish tank water pump inlet to ensure effective flow and avoid blockage Maintenance: Rinse or the cube every 36 months to preserve filtration efficiency Orientation: Do not place the grid filter downward Use scenarios Regular maintenance for a community freshwater aquarium: keeps water clear and reduces buildup of dissolved impurities between water changes Newly set up tanks or after large feedings: helps control turbidity and maintain a healthy, visually clear environment Tanks with higher filtration needs (stress for fish and plants): complements existing filtration by adsorbing residual pollutants and improving overall water quality Specifications and attributes Function: Aquatic filtration and impurity adsorption to improve water clarity Compatibility: Designed for use in aquariums with standard filtration setups; should be placed near the inlet of the water pump or filter Size and form: Cubeshaped solid block; threedimensional honeycomb structure Material: Activated carbon Performance notes: Provides crystalclear water and supports a thriving aquatic habitat; installation and maintenance are straightforward to sustain filtration effectiveness Important handling: The cube is fragile; its fragility does not affect its efficient use; avoid downward orientation of the grid filter This description aligns with the product's original brand, specifications, models, and functions, presenting clear benefits, practical usage, and upkeep guidance in a professional, trustworthy tone.
