Gravity Filters

The Aquascape Pond Filter Urn is ideal for smaller ponds, including preformed ponds or container water gardens. Aquascape Pond Filter Urn can easily be incorporated into existing ponds with a 1/2" water hose connection, ideal for use with Aquascape Ultra or AquaJet Water Pumps.

The Cetus sieve is a totally new, bow screen pre-filter, made using the latest rotational molding technology. With all of its benefits and build quality, it is undoubtedly the best of its kind on the market today, regarding quality and performance! It is designed to efficiently and effectively remove large amounts of mechanical waste from a pond. It can be set-up gravity OR pump fed and has many benefits over the original bow screen technology. This Cetus has a variable inlet height using the unique patented Pondflow regulation system for use when gravity fed. This allows water levels within the pond to drop without causing the circulating pump to be starved of water. The Cetus will allow a skimmer or a bottom drain to accept vast amounts of waste without excessive cleaning needed to be carried out. The water must then be pumped to either a normal filter above pond level (Nexus Eazy/Eazy Pod) or to a pressurised filter. If pump fed, the sieve is placed above pond water level and then the exit water is gravity dropped into your main filter. The Cetus sieve is a bow screen pre-filter, suitable for pre-filtration of any biological filter including all pressured filters. It is advised that all pressurised filters be pre-filtered using a Cetus to reduce excessive backwashing and maintenance due to heavy solids.

A compact member of the Nexus family, the EazyPod is a mechanical and biological filter system for garden ponds up to 5,333 gallons or Koi ponds up to 2,640 gallons. The EazyPod utilises static K1 Micro, which provides enhanced biological benefits, even when using the EazyPod solely as a mechanical waste filter.

Building on the tried and tested technology that has been present in the world renowned Nexus, the team at Evolution Aqua have gone even further to enhance their number one koi pond filter. The Nexus 220+ and Nexus 320+ filters now come with a new filter media called K+ Media in the moving bed outer chamber for vastly improved biological filtration and faster filter maturation. The new Nexus+ filters are now supplied "auto ready", with factory fitted fixings already in place, making it even easier to upgrade to the Nexus Automatic Cleaning System.

The BioSteps Plus Kit is the basic model. This basic kit comes complete with the new BioSteps filter, MF-1100EZ submersible pump, 25 ft of 3/4" quality "kink free" hose and all connectors to make installation quick and easy!

Matala BioSteps-II filter maximizes Matala filter media performance. The rugged BioSteps-II contains an amazing 200 sq. ft. of surface area for beneficial bacteria growth. Combined with a cross flow design that traps and processes more debris at high flow rates, you get unparalleled mechanical and biological filtration for superior water quality.

The BioSmart Gravity Filters are a multi-stage mechanical and biological filtration system in a compact package, designed for medium ponds or for ponds with moderate biological load (some fish). During biological filtration, the water is channeled through a series of filter foams that create a special environment by allowing the settling of beneficial bacteria. During this stage, harmful ammonia and nitrites are converted to nitrates, which support plant life in the pond.

Flow through filters with biological and mechanical filtration clean and clear pond water which flows back down to the pond by gravity. Oase BioTec Screenmatic automatically separates debris using the self-cleaning screen, depositing coarse debris into the removable tray. High efficiency filter system features 3 different densities of foam harboring a variety of beneficial bacteria that remove harmful ammonia and nitrites. Qualifies for the Oase Clear Water Guarantee when paired with the proper pump and UVC Clarifier.
