IceCap Bio-Sphere Media Tower (SKU: IC-BSTWR)
The IceCap Bio-Sphere Media Tower (SKU: IC-BSTWR) is an authentic, structural filtration accessory distributed by CoralVue to maximize the efficiency of your biological sump media. Traditional methods of housing ceramic bio-spheres often involve packing them into nylon drawstring mesh bags and dropping them into a corner of the under-cabinet sump. Over a few months, these limp bags compress, turning into dense, muddy dead zones that trap raw fish feces, loose macroalgae strands, and organic detritus. This trapped sludge suffocates the underlying beneficial bacteria, starving them of oxygen and causing hidden nitrate factories to form. The IC-BSTWR entirely resolves this flaw by ditching the bag and organizing your media into an open-air "high-rise condo" framework.
Visually, the tower features a premium solid black acrylic base plate matched with nine crystal-clear vertical alignment pegs. By sliding your media spheres straight down over the rods, you lock up to 45 biological balls into clean, neat columns. This layout keeps the media separated and perfectly aligned in the direct path of your water current. Because water can flow effortlessly through and around every single piece of media from all directions, your nitrifying bacterial colonies receive a continuous supply of highly oxygenated water. This ultra-compact vertical array packs a full 1KG media capacity into a tiny square footprint, freeing up space in your filtration room while keeping your water parameters exceptionally clean.
Key Features
Prevents Sudden Salinity Shifts: Stacking your media vertically inside the sump means you can safely lift the entire tower out for a quick rinse during maintenance without spilling water or shifting loose pieces into return pump impellers.
Eliminates Channeled Bypass: Forces incoming water to pass uniformly over every biological sphere rather than tunneling around the sides of an unevenly packed media bag.
Transparent Acrylic Rods: Clear structural pegs stay hidden inside the central holes of your ceramic spheres, maintaining a clean, high-tech appearance in your equipment chamber.
(Note: This e-commerce item includes the standalone acrylic base plate and integrated rod assembly tower. Biological ceramic spheres, filter socks, and water booster strains are sold under separate product catalog lines).
