Thank you Vic!
- I removed all optics for a wider spread of light
- I replaced four whites on each side, eight total with blue (480nm) LEDs
- I run the photon for 12 hours a day, eight of which at 100% on both channels
I have mine the same way only I have 450's instead. I tried taking the optics off but it looked a little dim for me. How high do you have the fixtures? also how many t5's are you running? I have two, a coral plus and a blue plus.
- My lights are approx. seven inches off the water surface
- I'm running two 54 watt T5 bulbs also, coral plus and GE 6500K.
