Premium 4-Inch Aquarium Sump Filter Sock
Achieve crystal-clear aquarium water with our Heavy-Duty Sump Filter Socks from Atradesen.com. Designed as the absolute first line of defense in your bottom sump filtration system, this premium mechanical filter bag efficiently traps uneaten food, fish poop, and micro-particles before they can break down and foul your water quality.
🌟 Advanced Mechanical Filtration
-
Protects Your Bio-Media: By trapping solid detritus upfront, it physically prevents your expensive biological filter media (ceramic rings/sponges) from getting clogged! This ensures a highly stable nitrification system and drastically extends the time between deep sump cleanings.
-
Washable & Reusable: Made from durable, high-quality white felt/mesh material. It is incredibly easy to remove, rinse, and reuse, saving you time and money on disposable pads.
-
Easy Drop-in Installation: Features a sturdy plastic ring that drops perfectly into standard 4-inch sump filter holders or custom acrylic baffles.
⚠️ Sizing & Installation Guide
Please ensure this filter sock fits your sump dimensions before ordering:
-
Ring Diameter (Width): 10cm (Approx. 4 inches) - Ensure your sump's acrylic holder matches this hole size!
-
Sock Length: 38cm (Approx. 15 inches) - Ensure your sump compartment is deep enough to accommodate the hanging bag.
-
Installation Tip: Install this filter sock at the very beginning of your sump (exactly where the drain pipe drops the water into the tank) for maximum mechanical filtration efficiency.
