Evan,

Actually I was thinking the tub would be built out of plexi. That way you
could get the same level of light from all around as opposed to just from
the top (hence the reflective surfaced for the container). That way you may
get more even UV illumination on all the surfaces especially in the nooks
and crannies. Just a thought though as it may not improve or make things
worse.
