QUESTIONS!
1.
I am liking the light but it's difficult coming from all T5s to know if I am setting it right. I have a PAR meter and it's as strong at the bottom in a few spots as it is at the very top! How do I avoid the real hot spots? I have the outside LEDs 10% lower than the middle to even it out a bit but still getting too much light at the bottom. Running at 40% on the outsides and 50% in the middle.
2.
Do I need the white LED, or is the blue and royal blue, with some violet enough spectrum for the corals to grow? I also have 2 ATI Super Blues and 2 Purple Plus T5s during 4.5 hours peak time.
My combination for daytime is BLUE:200 ROYAL BLUE:255 VIOLET:150 WHITE:20. 4-T5s @ 100% (stillburning them in. Would like to lower them to 75%)
Any suggestions to improve coral health and growth and visual aesthetics?
