Gravity Filters

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.

• Innovative Flow-Through filter design provides maximum oxygenation
• High-surface area filter foams provide exceptional biological filtration capability
• Distinct filter zones promote the settlement of a variety of beneficial bacterial responsible for different phases of the nitrogen cycle, which increases the conversion of harmful ammonia in your pond
• Advanced features include the built-in cleaning indicator notifies you when the filter needs cleaned and water temperature display tells you the water temperature at all times
• Cleaning handles for convenient maintenance allow for easy cleaning without needing to remove or manually unclog the filter foams
• After clearing the filter foams, the sludge drain can be opened for easy removal of coarse debris from the unit
• For best results and clear water guaranteed, use with an appropriately sized OASE pump and UV clarifier

Flow through filters with biological and mechanical filtration clean and clear pond water which flows back down to the pond by gravity. Oase BioTec Screenmatic² 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.

Features:

• Intelligent cleaning sensor senses debris and activates cleaning screen
• Manual belt run button for manual operation of cleaning screen
• LED indicates status of cleaning bar and screen
• Rubberized separator lip scrapes debris off screen and into tray
• Removable sludge tray for easy maintenance
• Built-in overflow holes keep filter operational even when sludge tray is full
• Sludge drain with integrated slide valve removes sludge and dirty water from system
• Optimized water distributor evenly disperses water flow over screen
• Add an optional Bitron C UVC clarifier to any ScreenMatic² filter system for enhanced clarity and cleaner water

Advanced filtration systems for Koi ponds now with NEW K+ Media

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.

How the Nexus Works

Water from the pond enters the nexus via the inlet into the inner chamber which works as a vortex, allowing larger solids to settle out. Water then passes through the grills in the stainless steel “Eazy” filter, where the finer particles are removed by the static bed K1 Micro® filter media. The clean water then passes to the outside chamber of the Nexus for biological treatment before returning to the pond. At this stage, biological breakdown occurs through different strains of bacteria and filter feeders living on the protected surface area of each K1+ Media filer. The bacteria convert Ammonia and Nitrite into less harmful Nitrate. Water then passes through the exit grill into the outlet and returns to the pond.

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.

• Mechanical and biological filtration.
• Very eazy to install and operate.
• Quick and eazy cleaning cycle.
• Works equally well pump or gravity fed.
• Ideal as a filter on a quarantine system.
• Also ideal for use as a pre-filter, polisher or on a skimmer line.

The EazyPod Automatic is a self-cleaning, mechanical and biological filter system for ponds up to 2,640 gallons.

The integrated control box contains an adjustable timer which initiates a cleaning cycle automatically - meaning your filter will clean itself even when you’re not there! Inside the control box, the electronic connector blocks control the automated waste valve, along with your choice of circulating pump (not supplied). It even houses an integral air pump which kicks in automatically to clean the K1 Micro media.

Crystal clear, healthy water is achieved by K1 Micro filter media, which also provides enhanced biological benefits by way of its protected surface area.

The Eazypod UV Automatic features an integrated 18 Watt UVC built in to the inlet section of the filter, helping to clear green water. Available in 2 models, users can select either the EazyPod Automatic or the EazyPod UV Automatic (with built-in 18 watt UV). 

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.
