LED for LPS

[DarthSimon]

Hey guys,
I am currently running the Chinese knock off LED light fixtures on my 220 reef. There's apppx 100 bulbs. 50 blue and 50 white. 1 watt bulbs.Tank is 30 inches high and lights are about 4-5 inches above the water line. I can't seem to keep most LPS. I buy lobos, wellsos, chalice.
Within days or weeks the teeth just start popping through and I loose the coral.

For flow I'm running 2 Vortech MP40's.
Nitrates are close to 0, phosphates are 0. Alk is 8. Salinity 1.024. Calcium 420

What am I doing wrong? All the soft corals on my tank thrive.

Am I starving the corals? I put these lps close to the bottom. Also tried up higher.
Nothing is working.

I've tried target feeding. Corals are so stressed they don't take good in.

Any advice were to go? Better light fixtures? AI? Radion?

Better light would help a lot, go with some Razors

That fixture isn't enought you need 3W leds and more with a 30" depth tank. I have 72 leds on a 125g custom tank, 22" depth.

Kessill?
How about 3, 350's?

 

[nanoreefer1000]

I kinda like them, how long and wide is your tank?

 

[DarthSimon]

6 feet wide, 2 feet deep, 30 inches high.

"I buy lobos, wellsos, chalice."

I am sorry to say that leds are not appropriatte for the kind of coral you try to mantain: for one or another reason they do not get the kind or wave length they need and they perish afetr some time.

The evolution is that they get orange then light brown then they die.

Nevertheless there are other corals that trieve with your fixture: goniopora, plerogyra, fungia, duncanopsammia, and SPS.

That is my experience and the experience of many others but there will be oher people that will not agree. I only speack taking into account my experience.

Usually i am just a lurker but with that i have to make my first post..he cant keep low light corals alive and you want him to try sps? Not only that but gonipora have one of the worst survival rate in the home aquarium unless you get an ora red type.

It has nothing to do with the light level being too low, it has to do with certain LPS not getting the spectrum of light they need from LED fixtures, particulary those that are the common blue/white variety.

I am using the Ecoxotic Panorama Prod modules for my 90g LPS dominant tank. I run 6 12k/453nm modules at about 65 pct power on a dimmer. Work like a charm.

FWIW, I have acans, hammers, polyps, and SPS under LEDs. Were previously under T5s and halides before that. Acans were eaten to skeleton by my angel and are now regrowing under blue/white LEDs. LEDs are 3w ran at 2w, 453nm and 460 blue, 10k and 14k white are the colors. 40 LEDs over a 30 x 30 inch area....depth is 20".

Someone once told me, "You will never grow corals under an LED fixture." :rollface:

I disagree 1 billion percent. I had LPS under T5s and my growth was adequate...it was not until I added LEDs that my growth took off.

See for yourself.

Hammer before LEDs.

Hammer after LEDs.

LEDs do work well just like the other lights out there, but there is bad with the good on all of them. LEDs can turn LPS orange I have mainly seen this happen to red acan, but I have seen it happen it a pink chalice as well but I like orange acans over red so I wouldn't mind.

 

[chrisfont23]

You need the 453 or lower end blue wavelength to promote coral fluorescence. Without it, you may wind up with an orange coral. LEDs are not for the hobbyist who relies on others to provide the answers to their questions...if you are skeptical about purchasing LEDs and do not do your own due diligence you are setting yourself up to fail.

I did not have that problem. I did a load of research, contacted numerous manufacturers, studied up on wavelength, PAR etc., and put in my time and wound up with quite a retrofit canopy unit for about $1000.

 

[nanoreefer1000]

So you did a ton of research on spectrum, etc and you ended up with a fixture with only 12K whites and RB?

What is the research that supports this claim? This could be one of the worst posts I've ever read.

I would disagree about the 453mn fluorescence. Take superman montipora for example, it emits strongest florescence at 489nm and 611nm peak for polyp florescence. M. undata excitation occurs at 490nm.

[victor escobar]

I did not say taht you cannot keep any coral under blue and white led only some species are not appropriatte for this fixture. I agree with Ptyochromis that you we need certain wave lengths on the UV or the red part of the spectrum (there are different ideas on that)

For the one that wrote the best post of the history (pwoler) please read that:

"leds and LPS color changes" there is some interesting information, of course it is not research but close to it.
