What do u guys think

[Craigar]

So I just got two true lumen 48" LEDs and trying to figure out what to do with them do u think one would be good over my refugium? They are 2:1

If you fuge can hold a small frag set up, sure. Otherwise the blue won't help the micro algea.... but if you got it, use it is what I'd say.

Or trade them to me for some frags.

I use a 120w 2:1 (17-420nm, 17-450nm & 21-10k) led panel on my sump and it grows macros like crazy, esp dragons breath!

Although I guess you could make the argument that the blue does nothing and its just the whites growing things. However I think its both the red and the blue spectrums that chlorophyll absorbs and is used for photosynthesis. But really what the heck do I know, I'm no scientist

Red triggers algae growth badly.. Blue is what grows corals and white is mainly for aesthetics. (looks)
But sure.. white light does grow corals just not as effectively as the blues.

What research do you have to back up your claims? I'm reading more and more that red is an important part of the puzzle to get things to grow. You just have to use the right amount so it doesn't over power everything else.

we had a Scmas meeting and had a guest DIY led guy whi brought his research. Do you ever check the springs forum?

 

[cdrewferd]

Nope, sorry. Just the national ones. What was his name? I'd love to read his research.

Red light also causes corals to BLEACH and DECREASES coral growth. Fun facts

Here's the research supporting my next DIY LED project

The problem with RED research is that it was done like 10 years ago. So i find it hard to base stuff off of research that is outdated in our field.

 

[cdrewferd]

Here's a good read.

Sorry Craig, back on topic.

I'm not sure they will give you the growth you want in your fuge. You can always rig them up and try though. If you are happy with the results you can make a more permanent mount for them.

I know several people running red in their lighting with sick colors and growth. All in moderation my friend. Look at the Ecotech Radion. I seriously doubt they would have incorporated red into a $750 light and probably the tens of thousands if not more in R&D/manufacturing to produce a light that uses a spectrum that there was definitive proof always causes corals to bleach and decrease in growth.

In fact I had more algae growth in my display when i was using an AI nano sol with only whites and blues than I ever did with the Radion which also incorporates red and green. Do I think too much red would cause a problem? Of course but so does too much of anything in this hobby.

 

[reefmaster719]

There's always going to be crooked research. Maybe they had phosphates in the water or high nitrates? Who knows. We may never have proof... Just here say and what to believe. I didn't come up with the research but its interesting to think about.

 

[Craigar]

Well I guess I'll give it all a try and see what happens I have a 36" single t8 fixture over it now so it should be better than that
