If you're measuring underwater I don't think you'll need to worry about infrared. In a dry tank you probably need something but I'd try the green gel first before working on the infrared part. In an otherwise subdued light room you'd be measuring the output of flourescents which don't have any significant IR output to measure. If you're measuring incandescent or MH that's a completely different story with lots of heat output.

Good luck!
