Just to catch up on this question :im thinking of swaping a blue for a violet on the nano Ibox. cyan is a no no from what i have read. does anyone else have information on this? would realy like to see some information
I have been thinking of adding some additional spectrum for a while. A couple of things have convinced me that it is worth a try – 1) a number of higher end commercial units are new employing violet LED’s and 2) a recent article by Bernhard Jasiek in the Sept/Oct 2011 Coral magazine.
Bernhard is currently running a 6.5ft tank with the following LED combination:
- 90 Blue 50%
- 45 White (6,500K) 25%
- 15 UV 9%
- 15 Cyan 8%
- 15 Red 8%
I am currently running with 60 LED’s over my 4ft tank with the following combination:
- 30 Cool White (2 different bins) 50%
- 10 Royal Blue 17%
- 20 Blue (2 different bins) 33%
- 10 Cool White 17%
- 14 Neutral White 22%
- 10 Royal Blue 17%
- 10 Blue (2 different bins) 17%
- 4 Cyan 7%
- 8 Purple 13%
- 4 Red 7%
· Driver 1 – 5 CW + 7 NW
· Driver 2 – 5 CW + 7 NW
· Driver 3 – 6 RB + 6 B
· Driver 4 – 4 RB + 4 B + 4 Cyan
· Driver 5 – 8 Purple + 4 Red
I am not saying this is going to work, and I am open to any suggestions, but I think it is worth a try.
