Rectangular Seafood Tank Systems

Available in single-tank and dual tank-models, Marineland Rectangular Systems are mobile, freestanding units ideal for application in a wide range of display scenarios. Because they don’t have to fit into a particular case or preexisting configuration, Rectangular Systems can be placed in corners, against walls, virtually anywhere for maximum effectiveness and/or convenience. And many Rectangular Systems are available with our patented Marineland BIO-Wheel®.

Need a lobster, trout or catfish tank? Marineland has a variety of rectangular seafood tanks to choose from.

Our BIO-Wheel filtration module provides a simple, yet superior solution to three-stage system filtration. Easy to install, easy to maintain, it significantly reduces labor cost while dramatically increasing filtration efficiency.

As water enters the module, waste is mechanically trapped by a poly-fiber prefilter pad. The carbon filter pack contains Black Diamond® premium activated carbon for chemical filtration, efficiently adsorbing dissolved organic compounds.

Passing through the filter media trays, water flows onto the BIO-Wheel wet/dry biological filter mounted below. Because system flow causes it to rotate, the BIO-Wheel is constantly exposed to both water and air, thus developing a thriving culture of aerobic nitrifying bacteria.

  • Reverse Flow Filtration
    Prevents compacting of the filter bed, ensuring cleaner water and eliminating the need for periodic filter bed maintenance.

  • Refrigeration Unit
    Maintains tank temperatures of 45-70°F and can be preset to the exact temperature required by the system.

  • UV Disinfection Unit
    Helps stop the spread of free-swimming bacteria, algae spores and disease throughout the system.

  • Protein Skimmer
    Employs heavy aeration to remove dissolved organic matter from the tank in the form of foam.

  • Sump-level Indicator Light
    Glows red if water in the sump drops below desired level.

All systems also available in 220/240V, 50 Hz.

Many of our systems are available with Marineland BIO-Wheel wet/dry biological filtration. BIO-Wheel improves system water quality, lowers maintenance and increases holding capacity.
