siwelk Posted May 21, 2012 Share Posted May 21, 2012 ~*Welcome*~ So, I won a $25 gift certificate from MakersLED at the Reefstock raffle back in March. It will be used to build a fuge light in order to maximize growth of various macroalgae.

LongPig Posted May 21, 2012 Share Posted May 21, 2012 Nice. I'm thinking about getting one of those heatsinks in 36" to do a build to replace the lights on my 40 breeder. Link to comment
siwelk Posted May 23, 2012 Author Share Posted May 23, 2012 Apparently I have a reading comprehension problem. The gift certificate was FROM makersLED FOR DF&S/Liveaquaria. Surprisingly, I was contacted by someone at makersLED and they offered to trade the $25 credit. Very nice. Good customer service prior to being a customer. Link to comment
ajmckay Posted May 23, 2012 Share Posted May 23, 2012 Well that's nice of them. It's 2x the cost of a regular heatsink, but I'm really liking the looks of this one and particularly the quick assembly... Not to mention I would probably spend double the difference in fabricating a holder/enclosure for a standard heatsink. I'm excited to see this build as I haven't seen much yet on this heatsink. It's just such a good idea IMO, I wish I would have thought of it. Link to comment
siwelk Posted June 7, 2012 Author Share Posted June 7, 2012 Haven't ordered yet due to production delays. Also, switching to CREE XP-E red as available. Link to comment
jedimasterben Posted June 7, 2012 Share Posted June 7, 2012 660nm is more important to photosynthesis than 630nm is. Link to comment
siwelk Posted June 7, 2012 Author Share Posted June 7, 2012 I've spent some time on various ATS sites looking for a consensus on an array. It seems to be pretty well documented that people are having success with 660. I think I'd like to try using 630 for their 'higher intensity' and see what happens. I'm also considering doing 6x 630 2x 660 & 2x 420 and ditching the 455s altogether. Given the modularity of the heatskink, I'm going to play this off as an experiment. I appreciate you help however, at first I wasn't aware that the CREEs were ~ 630 nm. The more people there are using a particular method, the more likely I am to try something different.

HecticDialectics Posted June 7, 2012 Share Posted June 7, 2012 Haven't ordered yet due to production delays.Also, switching to CREE XP-E red as available. The 660s are only a week out. Is your tank going to crash and burn because it doesn't get a new fuge light in a week? Wait and do it right, imo. Intensity doesn't mean anything if the wavelength isn't optimal. Your money to experiment with tho, just my opinion Link to comment
OneTrickPony Posted June 7, 2012 Share Posted June 7, 2012 I would check out the warm whites also they cover a lot of the wavelengths Link to comment
jedimasterben Posted June 8, 2012 Share Posted June 8, 2012 Intensity doesn't mean anything if the wavelength isn't optimal. This, this, and a ####load more this. 630nm hits a small peak in chlorophyll b, but is next to nothing compared to the peak at 660nm for chlorophyll a. I still can't figure out why Ecotech put the Cree in the Radion. Link to comment
siwelk Posted June 8, 2012 Author Share Posted June 8, 2012 Wait and do it right, imo. That's what I'm attempting to figure out. What exactly 'right' is and how to achieve it. I've mapped points from a couple graphs here: http://algaescrubber.net/forums/showthread...ull=1#post17563 And I'm currently thinking along the lines of: 6x 660nm 2x 630nm 2x 615nm 1x 470nm 1x 420nm If my current DT build is any indication, these plans and ETA are extremely tentative.

jedimasterben Posted June 8, 2012 Share Posted June 8, 2012 Honestly, for simplicity's sake, I would just do cool white and deep red LEDs. Link to comment
jedimasterben Posted June 9, 2012 Share Posted June 9, 2012 What about the OCW LEDs What would those do? If he's already adding deep red and cool blue (proposed), the green from turquiose would do nothing at all. Link to comment

The growth will be fine with that to experiment with. From what I know the 4:1 of the 660nm to 455nm will work. The 660nm is the main source you need. Ill be trying a 4:2:1 ratio of 660:420:455 to see what I can get. Link to comment
Deckoz2302 Posted June 9, 2012 Share Posted June 9, 2012 actually....algae uses 630nm... not 660nm for photosynthesis. Your build should consist of natural white and 630nm's for your best fuge growth. 660nm are what corals use. Link to comment

Jacob042426 Posted June 9, 2012 Share Posted June 9, 2012 no. I have PM disabled oh, well i sent you an led question. Link to comment

I am having trouble finding anything that proves corals need 660nm. I only see that in higher plants. From what I understand red light filters out in the ocean after a few meters. Thanks, Robert Link to comment
siwelk Posted June 10, 2012 Author Share Posted June 10, 2012 I would check out the warm whites also they cover a lot of the wavelengths I'm trying to realize growth using a few particular spectrums. No whites. Honestly, for simplicity's sake, I would just do cool white and deep red LEDs. I don't recall stating simplicity was a requirement. Link to comment

Thanks, Robert Photosynthesis is not coral-specific, zooxanthellae will use any wavelengths provided. Throw a deeper water coral that is only use to 400-450nm and give it a range from 400-700nm and it will use what it "knows" and will also take advantage of the new wavelengths provided. I don't recall stating simplicity was a requirement. Link to comment
