Okay thank you for that link it was really helpful : ]
I'm glad I didn't use a blacklight then I don't want to hurt my little Io. I found that my search results were mostly bringing up a lamp and the bulb together which was usually 80$ so I looked at just the bulbs and they were only about 20$ ^^

I'm still worried about her salt sneezing, about how often is normal? Is there anything I can do with her diet to reduce it?

And again thank you very much for your advice
