I use my orange glasses, and put my iphone against the glasses to take a photo in blue light. It works well. You don't need any crazy lens, but those lens kits also works well.
After five years without a display tank( I had a few frag tanks running well I was setting up my display), I finally got this IM 200EXT display up and running.
