| Re: UV Sterilizer - Suggested Flow Rates
The longer the water remains in the UVC, the greater is the effect, the more bacteria and germs are killed. The faster the water the UVC passes the LESS germs and bacteria are killed.
A Quite simple, easy to understand and logical circumstance in my view.
In contrast to Marine Depot I do not sell a UVC as expensive as possible. However, I have tested at the University of Frankfurt with some students different UVC with different flow rates, the result stands in MY Chart and is based EXCLUSIVELY on sea water. We have really counted out bacteria and germs in a dedicated quantity of water for every tested UVC after 24 hours of running time. The results are to be read up in the Chart.
Of course would be also killed bacteria and germs with a quicker flow rate and higher wattage of the UVC but not so effective and with substantially higher costs. (power consumption, purchase price; spare parts)
In Germany we have a saying: " Why with doves to throw at sparrows "
My recommendation for a 360 gal. Aquarium is 18 watts UVC, used in a separate circulation with a small pump (240 gph) 24/7 in your sump.
BTW ... I am use a 11 Watt 24/7 for my 225 gal FO. |
