Lighting and that mysterious gray film

About the lighting:
1. Price is terrific if it's for PowerCompacts - you never said, but 55w
is a typical 24" PC wattage.
2. Most of us don't need to make this kind of purchase very often, meaning
you'd most likely have a slow return on your investment. 250 2-lamp units
is a LOT of units.
By the way, I was visiting a LFS this afternoon (Albany Aquarium talking
with Guy when you called him - small world). I noticed that one the many
planted tanks has a light-gray film floating on the surface similar to what
you described a few weeks ago. I asked the knowledgable owner about this
and he said it's likely a combination of algae and dust, but it didn't
matter because it's easily removed. How? Turn off your water circulation
and float a piece of newsprint on the surface. When you remove it the gray
film comes with!
