I think you are thinking of pond keeping fish keepers. Water does not go green in a home aquarium, only the gales unless in very bright sunlight. Clarifiers do very little for clarity in the home aquarium.
Having said that, anyone buying a CLARIFIER probably buys it for an assumed clarity....they should be called green water clearers as that is what they are designed to do.
Those who buy a STRERALISER buy them for bacteria control.
I am not aware of any product sold for home aquaria that is sold to clear water or marketed as a UV clarifier all uvs that I am aware of for aquaria are STERALISERS but I have not been in the trade for some time. I imagine some marine keepers use clarifiers to control free swimming algae.
The majority of uv correctly understood and used in freshwater aquaria (remember we are in a stingray forum for freshwater species) are used for bacteria control, very few would be for clarity of water if understood.
I use two in series for maximum exposure time and they run from the sump on a small dedicated pump which returns to the start of the sump on a slow feed, this way there is a good deal of re-circa within the sump...all of this is for bacteria control.
