I have 2- 4x4' sheets of 3/8" Starphire that I'd like to build a large skylight with, and possibly use gels to "tune" the light for better color.
Do you see any drawbacks?
Thanks for sharing all of your research, and taking time to communicate with those of us with a lot to learn !

Ive done that actually. In Chicago, a 8'x8' 1500g tank with a 6x6 area of skylights over it. I used 3x 12"x72" strips (a 36x72 sheet) of transparent blue acrylic to filter 1/2 the light coming through the skylight... very effective. Sure, it cuts down the total output, but its not like it matters... its a huge skylight! Otherwise, the 40-some blue and actinic T5 bulbs over the edges of the tank fill in the rest.
