Evolution Aqua Pure Pond

Pure Pond is our Award Winning bacterial product that helps to maintain crystal clear and healthy pond water.

PURE POND are biodegradable balls, crammed full of live bacteria and enzymes that when added to your pond filter get to work breaking down Ammonia and Nitrite, whilst cleaning up organic waste.

The bacteria and enzymes are slowly released when they are needed most to address biological issues in the pond that are often the cause of poor clarity.

PURE POND balls work particularly well within the Nexus filtration system helping to smooth out any peaks and troughs in the Ammonia / Nitrite cycle. Simply add the balls into you biological chamber, ideally held within a filter bag, where they will agitate alongside the K1 Media.

When using PURE POND balls as a maintenance product, especially when added once a month into your filter, the balls will help to maintain crystal clear and healthy water.

Please note PURE POND is not intended to clear green water. An appropriate UVC is recommended to clear green water.

One PURE Pond Bomb is effective on ponds up to 20,000 litres. Simply drop the PURE Pond Bomb into your pond filter or directly into the water as and when necessary. The bacteria and enzymes will react to the biological issues with in your pond. You cannot overdose with the PURE Pond Bomb.

When starting up a new filter, simply drop the PURE Pond Bomb into the biological stage of your filter. The high concentration of bacteria will help to remove the harmful ammonia and nitrite, allowing the filter media to mature.

evo UV

All new professional UV clarifier range

The new Evolution Aqua evoUV deliver a more efficient and more economical performance than before thanks to their new design. 

The new range includes completely redesigned 30 Watt and 55 Watt models, a new 15 Watt and 25 Watt model perfect for use on the smaller garden pond, along with a 75 Watt version

5 models including a 75 Watt UV

The top end 75 Watt model is designed for ponds up to 75,000 litres. The highly efficient ballast and high output 75 Watt UV bulb provides a more economical option than a traditional 110 Watt UV due to the greater UV contact time offered by the 1.2 metre bulb – ultimately saving you money! 

The evoUV pond clarifiers are manufactured in house by Evolution Aqua, continuing our long tradition for manufacturing exceptional pond filtration equipment right here in the UK.

More efficient design

The design of these new UVs optimises flow rates and improves energy efficiency, with the sole focus to deliver optimum performance at all times to clear green water in ponds which is caused by single celled green algae. 

evoUVs will work alongside many different filtration systems and are incredibly easy to install with flexible hose or hard pipe and can be easily fitted within existing pipework runs. 
All evoUV models come with high output UV bulbs powered by energy efficient ballasts, all housed within a fully watertight, robust housing.
