Well I lost my pump on my skimmer so my scrubber pump got robbed to run the skimmer after only around a week of running. Things were looking pretty good but I want to do it better this time. Before it was a 20*13 singel sided with 2x23w cfl scrubber. But now I am going to just break out the guns and go all out. I know how to work with acrylic and have all the tools to do it. so that said I am sure I can handle the body. The next thing is lighting. I was thinking LED's especially with how cheap you can get them now. So my thoughts were:
1. would 660nm leds be good enough for the red
2. Is there any benefit to adding royal blues or any blues for that matter
3. Warm white to add the slight blue and some other red wavelengths
4. How many 3W led's
5 any practicle reason for optics
I am going to ditch the fuge and use the tank as my outer housing perhaps ditching the acrylic build all together and just making sealed light boxes with just air in and out the only openings (led's dont need replacing but might need that if they are cheap.) The real odd thing is that reds have a significantly lower voltage than blues and whites for 700ma. So I need to figure out the ratio of red to whatever then plan my circuit accordingly. I will be using a meanwell eln-60-48 with 14 or so in series and two parrallel (ballanced) paths. The way I will wire it if one goes bad it will only cook one other. That driver does 48VDC with 1.3A adjustable so I will probably set it at 600ma just to prolong the live and lower the temps alittle bit. I will run the same screen but 20" being the width.
