oceanbound said:are their types of blacklights that dont give off uv light??
i need cuttle said:this is a very stupid question, and i knew the answer to it, but what percentage of acentic light is uv, and would all acentic be harmful?
Jean said:UV can be harmful, especially if you're planning to breed, it can cause mutation in larvae. There was an aquaculture facility here that used UV sterilization of water in their abalone and rock lobster hatchery and they were experiencing fatal mutations in their abalone larvae and hugely increased moult death syndrome in their rock lobster, once the UV was removed the problems more or less dissapeared.
oceanbound said:so why do they even sell blacklight leds for aquariums if they are useless?
main_board said:UV sterilization is actually a really effective and environmentally friendly way to sterilize vast amounts of water. I wonder if they experienced problems because the lights weren't housed correctly and UV radiation was allowed to leak out. I was just curious as I'd hate it if people got the impression that using chemicals and the like to treat water instead of UV is a better alternative, because I don't believe it is.
