Will too much light cause darkening of sps ??
- Thread starter chercm
- Start date
no usually the opposite, too much light will make them lighter.
I am not how long you have been on LEDS, but when my brother changed from his ATI PM to vertex LED his corals darkened for a month or so due to the shock of the change.
how long have you used the LED?
did you change recently?
does your LED have any red spectrum? Pinks can suffer due to the missing spectrum.
my brother used CIE Chromaticity Meter to measure the light spectrum ($10,000 piece of equipment) on his vertex with the following results
and just for reference here is his birdsnest under T5
and under LED 75:100:100 (w:b:rb)
he will be adding some red and violet leds when vertex release them in Aus to get the pink pop back in the birdsnest

I agree with the above statements.
Too little light = darker color
enough light = lighter colors or color stays the same
Too much light = fading colors or bleaching
When the corals don't get enough light (food) for them from the light their Zooxanthellae start to reproduce more causing more brown to be put into their flesh so that they can get the food they need.

how long did the coral recover from the shock ?

Try dimming the LEDs for a few days and see if that helps.

Too little light for sure.

what do u mean i left the LED at 10cm above water level ?

Pink birdsnest is a light hangry one. I suggest that if you can, get a PARmeter and see what PAR do you have above it.
Only with this mesure you will be sure about it but, keep in mind, too much light DON't dark any SPS.
O suggest you get lenses to concentrate your light over it. Maxspect is not what we can say a light penetration monster, specially without lenses.

YES! Too much light CAN cause your corals to brown out. The algae (Xooanthellae), that lives inside the corals, can become "too concentrated," as it reproduces. More light can make it reproduce faster. That algae is a dark brown color. A higher concentration of that dark brown algae can result in a brown coral.

Well, thats new for me. Zooanxanthelle can reproduce with nutrients (NO3 or PO4). That's what I learn since I began with salt aquarium.
I stand on what I said. Low light in your case OR too much nutrients or phosphate

approx 1 month
as i mentioned before i am not familar with the maxspec but if they are a quality unit(which i have heard) i do not think that they will be producing low light.
here is a PAR comparison of a 8x54ATI PM with 4 week old globes and vertex LED running 60%, the tank is 2.5" (75cm) deep
RED - ATI 8x54w
WHITE - Vertex Illumina 1200-200 @ 60%
As you can see a reading of 250 on the sandbed (75cm) is acceptable for most SPS.
we also PAR tested at 100% and it blew the ATI away. at the surface the apogee meter reads to 2000 PAR and at the light it was over. I do not have full list of these results.

Sanjay has data on Maxspec (as well as many popular LEDs on the markets):

still does not show the colour spectrum and wavelength of these units which is proven essential in coral growth and colouration.
according to the chap who did the CIE Chromaticity Meter test for my brother PAR is not an accurate measure for LED lighting as it can not pick up some wavelengths or something or other and it is emitting possibly 20-30% higher value than showed on the meter.
The tester is not a fish nerd but works in the electronis and lighting industry.

then i think i will wait for them to recover ..
