Royal Blue LED's?

[rosshamsandwich]

I don't like the look of red. Do I absolutely need REd? will the corals suffer without it???

You do not need Red at all. In Nature the Red Spectrum is virtually gone deeper than 45 feet.

I like just a little to highlight my Red Carpet Anemone.

Too much you would provide fuel for nuisance algae

Bill Thank you so much for your input. I am going to remove my Red Leds tomorrow with confidence. Again, thank you! Really appreciate your contributions

Red is not needed but some sps come from Shallower water and even though they do not like red they can develop colorful pigments and proteins to block it. So a little can be good.

Red is used by zooxanthellae algae

That said the zooxanthellae algae in corals do very well with only 400nM to 500nM Spectrum... Back in the day our Birdsnest Frags grew well using only 450nm Royal Blue...

Just a reminder in tropical reefs the <600nM is rather limited...

For those with a Refuge Red Is Important... Macroalgae like Cheato are shallow water and do better with this.

Battle Corals grow their frags in shallow tanks under 400 watt MH....Well over the 500-600 PAR that starts photoinhibition... Say 3X that +...

Not sure today but back then their MH Bulbs had plenty of the warm spectrum... No Nuisance Algae due to regular maintenance of frags and aggressive skimming to reduce nutrients...

For SPS Strong Light is good as the reflective pigments that protect the SPS from too much light often result in awesome colour from the pigments that reflect this light...

For LPS and softies its a simple modification of the number of zooxanthellae algae... That said I would bet that some genus of Euphyllia also use reflective pigments in shallow reefs.

Just a bit of food for thought...

Fact of the matter is some corals depending on the depth have adjusted to not having red light because it is filtered out pretty quickly. Photosynthesis is different for corals than plants because corals have adapted and are able to use proteins and pigments to block or even change the light for their use. If photosynthesis was the same for all corals they would all grow at the exact same depth.

Now I do think some red is beneficial but it is not needed though.. I think for sps it is a must for color.

Its all personal preference.

I like 3:1 or 4:1 Royal Blue to Blue to this some 410-430nm and maybe one or two 660nm photo red dialed down.

I'm currently working with this guideline and I'm loving the results..Thank you!!!!!!!!!!!!!!!!!

Waht's the easiest way to make your own led light fixture??? i need driver, heatsink, pcb board, and leds?
