Changing reefbreeders spectrum. Input needed before I order.

[Salty_Box_Reef]

I have been kicking around getting a value fixture and been reading a lot of good feedback on them from owners, but I have also noticed several people say they would like to or have swapped out a few led's to change the spectrum some. I would like to get some feedback on what you would change if you were ordering a fixture from them? It will be mostly a softy/lps tank for now but might move to a nem/clown tank in the future.

Steve,
I got 3 D120's from EverGrow back before RB was selling value fixtures (the same fixture) and I did a custom layout. It was about 2:1 blue to white and I now wish I had gone more blue. At 100% power on the blue channel, I only had to get to 50% or where about, to make the tank look white. I think the ideal would be to have both channels at 100% and just get to a 10K or 14K overall look. And even at 2:1 or 3:1 I'm not sure I see any good reason to add in red and green leds. There are more than enough white leds doing that job already. Too much red aids in the growth of nuisance algae and too much yellow & green aids in red cyano bacteria. If you want, I can send you my excel spreadsheet. I'm also starting a new build of a D120 and it will only have 4 white leds. I can send that as well, but it's a rather experimental approach.

Spreadsheets are way over my head. I'm new to the reef hobby so without someone explaining the spreadsheet to me in detail I'm sure it would be over my head.

I would like to have the ability to make it fairly blue, and was considering ordering reef radiances dm-44e which is basically a 44led version of the reefbreeders setup. This is the standard layout.

LED LAYOUT:

CHANNEL/DIMMER ONE - 22 LEDS
12 White. 14K – 18k Kelvin
4 White. 5000K – 7000k Kelvin
3 Red. 660 nm
2 Cyan 530 nm
1 Yellow/Orange. 580-595 nm




CHANNEL/DIMMER TWO - 22 LEDS
9 Royal Blue. 450nm
9 Indigo. 430nm
4 Violet. 410 nm


So I was thinking of swapping two reds for two blue 450nm, and one cyan for a indigo 430 on channel one. Then on channel two doing 9 royal blues still but doing 7 indigo, and 6 violet..

This will be going over a 14g biocube for a while so there will be plenty of light, but I would like to do a couple pieces of sps at the top. I much prefer the look of more blue so I think this would accomplish it while still allowing growth. What do you think?

Drop the 1 yellow /orange as it does nothing. If the greens (cyan) are next to the reds either leave them be or get rid of both. The idea is red and cyan mix with blue to look white to your eye, but are still red, cyan and blue to the coral (they don't have our eyes). If the reds and cyans aren't close together, move them together. Corals don't need too much violet and contrary to popular belief, violet and UV don't make coral colors 'pop'. It's a variety of colors mostly in the 450nm-480nm blues (more or less). I can get you a list if you want.

Here is what mine looked like, and remember, I did this 11 months ago and I would do it quite differently now.
