So I have a NanoBox v3 retro kit in my T5 fixture. After doing some testing with a phone app lux meter (which I know is not the best option. But with all 5 channels at 100% 9" above my tank,at the water line I am getting a hair over 100 par. I am wanting to get some more light directed into the tank. Has abybody used these glass optics ?
