Evolution Aqua Tempest Filter

The Tempest Filter is an innovative polishing system for ponds that will help to deliver crystal clear, healthy water. Designed to be used in conjunction with most filtration systems, the Tempest offers additional mechanical and biological filtration. The Evolution Aqua Tempest Filter can also be used on quarantine systems or as a standalone filter on smaller ponds.

The Evolution Aqua Tempest Pond Filter is easy to install and is simple and quick to clean, by way of a unique, patent pending air syphon design. During the cleaning process, air is drawn into the filter as it empties which causes the water to agitate, effectively cleaning the K+Media.

Using Evolution Aqua’s K+Media as the filter media, particles down to one micron can be filtered. Not only that, K+Media is the result of extensive research and development, moulded with minerals for faster maturation times.

E A Tempest Filters can be installed on a variety of set-ups. On larger systems that require a higher flow rate, multiple Tempest Filters can be installed in a modular system.

Nexus Automatic System

Continuing our long standing reputation for innovation, the Nexus Automatic System now enables Nexus owners to benefit from a fully automated cleaning cycle on their multi award winning Nexus filtration systems. Physically turning ball valves and manually switching pumps on and off will now be a thing of the past thanks to the Nexus Automatic System. All of the key processes that form the cleaning cycle are now controlled automatically with this easy to install kit.

Overview

The Nexus Automatic System can be installed on Nexus 220 and 320 filters manufactured after 2006, whether on gravity-fed or pump-fed installations. The kit includes a control box which connects up to an automated
waste valve, airpump control box and an automatic inlet slide plate (for gravity fed models only). Once installed and connected to your pond pump and mains power the system will carry out cleaning cycles at timed intervals or when pressing the manual clean button.

Cleaning Cycle

The Nexus Automatic System will control the cleaning cycle fully automatically. Cleaning is done on a timer, which is factory set to clean once every 3 days, however, this is easily adjustable to fit in with your pond requirements. The Nexus Automatic System will run a cleaning cycle which lasts approximately 10 minutes.

 

Gravity Fed Cleaning Cycle

■ Adjustable timer kicks in to start a cleaning cycle.

■ Control box automatically switches circulating pump off.

■ The water level in the Nexus equalises.

■ Inlet valve closes whilst at the same time air is diverted from the outer bio chamber to the EAZY to clean the media.

■ After the media has been cleaned, the waste valve opens.

■ EAZY is drained to waste and inlet valve opens for a final flush of the EAZY.

■ The waste valve closes.

■ Air is diverted back from the EAZY to the bio chamber.

■ Circulating pump is switched back on.

■ Nexus returns to filtration mode.

 

Pump Fed Cleaning Cycle

■ Adjustable timer kicks in to start a cleaning cycle.

■ Control box automatically switches circulating pump off.

■ The water level in the Nexus equalises

■ Air is diverted from the outer bio-chamber to the Eazy to clean the media.

■ After the media inside the Eazy has been cleaned, the automated waste valve opens.

■ Eazy is drained to waste.

■ The automated waste valve closes.

■ Air is diverted back from the Eazy to the biochamber.

■ Circulating pump is switched back on.

■ Nexus returns to filtration mode.removed if needed with the K1 Micro in place. This added feature is ideal when undertaking further maintenance.

 

The generally accepted practice is that when you keep ornamental fish, whether in a pond or in an aquarium, to keep the water fresh, 10% of the volume of the water in the pond/aquarium should be changed on a weekly basis. With this in mind, we recommend that you set your Nexus Automatic system to run a cleaning cycle so as to exchange water in line with this.general parameters of our ponds is turn over rate. This is the time that it takes for the total volume of the pond to pass through the filter system once. We recommend that for ideal performance a turn over rate of every 2 to 3 hours is found to be best.
