Patrick M. Bodega Aquatics Posted September 29, 2020 Share Posted September 29, 2020 Hello everyone! After losing 3 of my cobalt discus due to parasites, a fish shop in northern California recommended a UV light to kill future parasites. Do these work? What brand do you use? I really don't want to drop $100+ on something that isn't worth it. Also, If you don't like UV lights, what is your alternative? Thanks! Link to comment Share on other sites More sharing options...
