“A great UV steriliser. In my experience when only running it to deal with bacterial blooms or pesky algae it makes a visible difference in much less than a day.
I now run it in the background all the time and together with other filtration systems it definitely helps to keep my water crystal clear. It's a compact unit and fits easily into my sump alongside my other equipment. It is also easy to maintain
Definitely a worth while purchase for added peace of mind when tackling issues with water clarity etc.”
