Pre-filter to remove waste & debris

The Cetus sieve is a 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.

Cetus Sieve

Overview

The Cetus Sieve is a self-adjusting sieve which can be installed either gravity fed or pump fed. The Cetus Sieve enables your pond water to be filtered of large amounts of waste and debris before the water enters your current filter system. This process is commonly referred to as “pre-filtering”. The Cetus Sieve can also be used as a stand-alone unit to remove leaves and other floating debris from your pond via a surface skimmer. The Cetus Sieve will efficiently and effectively remove large amounts of mechanical waste from your pond. The Cetus Sieve is compatible with all filtration systems, however it is the perfect prefilter for the Evolution Aqua Nexus filter range. For gravity fed systems the Cetus Sieve has a weir which will automatically adjust to the flow rate of your pump. (Max flow rate 18,000 litres/hr) When the Cetus Sieve is used in front of any other biological/mechanical filter the period in between cleaning will be extended. The biological process is improved by the removal of organic matter which would consume oxygen and leach ammonia and other compounds into the water.

How the Cetus Sieve works

Installing the Cetus Sieve The Cetus Sieve 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.

Professional ultraviolet clarifiers for ponds

Evolution Aqua’s pond UV clarifiers have been completely re-designed for 2021, to deliver even greater performance and improved serviceability. Our range of six evoUV pond clarifiers are made using the very latest technology and design techniques, ensuring there is even water flow through the unit, and optimum ultraviolet light penetration.

One new feature is the ease of the serviceability of the evoUV. Changing bulbs, quartz sleeves or replacing a ballast are quick and simple to do.

The evoUV is simple to install, with universal mounting plates allowing you to fix the unithorizontally or vertically, or at any angle you choose.

How the evoUV works

The evoUV range of clarifiers have been designed to clear green water which is caused by single celled green algae and prevent it from returning. They will work alongside many different filtration systems but when used alongside Evolution Aqua’s pond filtration systems, the evoUV will help to deliver crystal clear and healthy pond water.

Your evoUV professional quality UV can be connected to your pond pump and filter with flexible hose using the stepped hosetails provided, or you can install the unit using hard pipe.

Evolution Aqua Pure + Filter Start Gel

Evolution Aqua Pure + Filter Start Gel
£19.95 – £39.95

Live bacteria gel to start new pond filters

PURE+ Filter Start Gel is a live, concentrated bacteria culture for use in new pond filters. The gel based solution will stick to the filter media, allowing the nitrifying bacteria it contains to rapidly colonise your filter.

Once the filter media has been coated with the PURE+ Filter Start Gel, the beneficial bacteria within the gel will speed up the maturation of your filter media, while helping to convert ammonia and nitrite, resulting in less stressed fish.

DOSING ADVICE

• Shake well before use to ensure the bacteria has not settled.

• Unscrew the cap and pour the contents of the bottle directly onto your filter media for best results. You cannot over-dose your filter with gel.

• We always advise the addition of oxygen to your pond via an air pump and diffuser when using PURE+ Filter Start Gel.

• Always perform regular water tests using a suitable test kit, especially before adding fish to the pond.

• If a UV-C is running, switch it off when dosing and keep switched off for 12 hours after dosing.

PURE+ Filter Start Gel will not address problems with green water, a suitable UV-C should be used to clear green water.
