Evolution Aqua evoUV Series - Flow Rate and Sizing Guidelines; Optimal Flow Rate Recommendation; Model Selection by Pond Conditions

Your evoUV will keep your pond clear of green water up to its maximum capacity.
However, it is important to note that there are factors that affect how you select the
right size of evoUV for your pond.
You will need to take into consideration such things as stocking levels, sunlight /
shade, daily sunshine amounts etc. This is not always possible to calculate, and if
this is the case, use the tables below as a guide. It must be stressed however,
that these are only guidelines, and you should take advice from your local
Evolution Aqua dealer
USA - Southern States / Mediterranean 3 Watts UV per 1,000 litres
Northern Europe including UK 2 Watts UV per 1,000 litres
USA - Northern States / Canada 1 Watts UV per 1,000 litres
*evo110 offers even more UV per volume than the evo75 for more demanding situations
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.
