I can go up to like 4 feet above the tank with the light and I could use the reef keeper to not run at 100%. But I am afraid of to much spill over, that is why I was wondering if I could get away with the 24" with maybe the wider optics. The 24" is considerably cheaper also so I was hoping it would work.
The ray 2 was what got me looking at the LEDs. Only thing is I am already shelling out a good deal of money, I would rather pay a little extra to have sunrise/set. DIY would also be amazing but I do not have excel to find out the number and spacing of the LEDs. Plus I am unsure whether I have the knowledge necessary.
Thank you very much for your imput so far.
