uv
Cuts down on number of free swimmers but wont get rid of spots completely.
(can reduce the effect of some therapeutics like Malachite green and antibiotics like Oxytetracyline that break down in light)

yeah very true but with uv,s you dont need them ! or with the right combination with a small amount of the right chemicals you get rid of it alot easyer and have a nice clean tank. there is alot of good articals about uv,s and how hospitals and surgins use them and also third world countries for cleaning water, and there is some good articals in fish mag,s about white spot and uv,s and other harmfuls but i recon you cant beat them for nice cristal clean water and glass im sure any ones else who uses them will agree, as i found out the work for white spot by acident (unfortunaly i caused the problem myself) then read up about it and its true, i recomend people to get of the buts and buy one or two and give it a go and see how long you can go with out cleaning the glass on your tank
p s i wouldnt recomend any one to use Malachite green unless you want to kill all your plec,s ,catfish , loaches and stain all your air lines tubes and silicone and any plastic in the tank 8O tetracyline is good but also nasty but i have used it and i keep a bottle handy but like most meds uv is the same as carbon or some other types of media you just turn it of or remove it but personly in ime and imo you leave them on and use very small amounts of meds and you will remove any dramers in your tanks
