My Kindermann tanks are stainless with black plastic; use the same
Nikor reels as the reel Nikor tanks. They are _definitely_ UV tight;
most window glass is almost UV tight. I'm sure they are fine for the
IR that HIE is sensitive to.
Try to get at least an 89b filter; it is a lot more interesting than
the 25. An 87 is better yet, but then you are down to about EI25. Get
some gel filters and cut them to size to put behind a UV filter;
that's cheaper than ordering specific sizes in glass.
Note that for closeups you should open up a stop or two; and winter
also requires about a stop more as there is less IR bouncing around.
