Customer Review

After around 30 years filters and UV clarifiers had abandoned (from another manufacturer) their minds. The now Berlanfilter procured with integrated UV clarifiers seemed that the removal of algae concerned, this task is not to genügen.Nachdem I Berlan the UV-C light filters have bought this on a whim, the algae were gone, however, after a short time.
