Evolution Aqua evoUV, Installation And Operating Manual

The evoUV Aquarium UV steriliser can be used either as a clarifier, to damage water 
born green algae cells (green water,) or as a steriliser, to help to control disease 
pathogens. When compared to the evoUV for ponds, the evoUV Aquarium Steriliser 
comes with a narrower inner-pipe to ensure that the aquarium water is held much 
closer to the UV bulb as it passes through the unit. 

To be an effective steriliser contact time, as well as close proximity to the bulb, is 
key, so we recommend that maximum pump flows of 1,500 lph for the 15 watt  
and 2,000 lph for the 25 watt are not exceeded. Larger flow-through can be 
achieved although may not achieve the same result in terms of sterilisation. 

For larger system volumes or increased sterilisation capacity multiple units can be 
connected together with either flexible or rigid pipework (not supplied). For best 
possible sterilisation results use an over-rated unit with an under-rated flow rate, 
and replace the UV bulb with new every six months. Always combine with effective 
mechanical filtration to remove debris from the water and to capture dead and 
damaged algae cells. If using multiple evoUV Aquarium UV Sterilisers, connection in 
parallel, rather than series is advised for best sterilisation results.

FLOW RATES

Please note:

 For optimum performance we recommend that you pass the entire  

volume of your pond through the evoUV unit once every 2 to 3 hours.

We do not recommend the use of pumps with operating pressures in excess of 3 bar.
