leds and LPS color changes

I have a question. My tank has gotten leds and almost everything is becoming orange or green or blue. That is something that I do not like because it makes the tank more monotonous than it was. It is always the same I buy something red (lobo, cinarina, chalice, etc.) and they start becoming orange and then a bit greenish and all the same color. If the piece is blue then the blue intensify and if it is green then it becomes fluorecent green.


Do you have esperiences with leds and colors? It there any way to reverse the situation?
 
do you have any royal blues in the mix? they usually bring out the reds in corals similar to fiji purple T-5 bulbs.
 
What kind of LED's are they, and do you know the ratio of blue to white off hand? I have LED's and my reds pop :) It sounds like your corals may be lightening up a bit in color though, I've seen that quite a bit on fixtures that have too many white LED's.
 
Thank you for the replays. The question is not if I can see the red colors of corals (when just added to the system the reds are incredibly strong), the issue is that after the time the red corals become orange or green.

The system I've gotten is only white and blue 50-50 but I can control the intensity of both colors. Now I'm putting 70 % of the blues and 30 of the whites but things do not seem to improve. What is better to increase the intensity of the blues or the whites?

It is interesting to know that cyan/green leds or royal blues can make a difference.

It is going to be difficult for me to add any new line of leds but not impossible so I would like to have more opinions before doing it.

Have you had experience yourselves about that?
 
I'm kinda bummed too. I have two red acans that turned very orange on me. The leds made them look great then after a few weeks then they became orange. Also a red and green chalice that the red is almost completely gone but the green is nicer. It used to be 40/60. I have a red chalice that is getting very pale but I haven't had it long enough to tell if it will stay this way. I'd love to know the answer to this question. I wonder if it's a higher light issue, or if it's a spectrum issue. I have 2 Ai sol blues run at a maybe 18k from the start.
 
Has anyone else seen color changes? And those who have, what LEDs are you using (what brand, what color combo, etc)?

I'm seriously considering swapping to LEDs for long term money savings (currently facing having to replace my 3 250w radiums to the tune of $230 w tax). But not if I am going to have Acans changing colors on me!
 
It may not be your lighting. Check your iodine and potassium levels. These are connected to pink and red coloring in corals.
 
OK I accept that the chemistry is linked to the colouring of corals, but the estrange thing is the commonality in different tanks. I wonder whether the spectrum of the leds is too linear in comparison with HQI so they are missing some parts of the spectrum necessary for some color pigments such as red.

I do not know if all tabks are suffering the same or it only matters with blue-white led lighting
 
How long are we talking about here for a color change? I've got three colonies of red or mostly red acans that have been under 50/50 cree cool whites and royal blues since february; one has gotten a bit less orange and more red, one has gotten a green cast to some white spokes, and a third has added a bit of a blue rim, but the reds are (if anything) a little redder...

I've got them in a slightly well less lit spot between my two fixtures -- one colony I had in a substantially brighter area for a few weeks, and it was noticeably unhappy -- heads held tight against the skeleton. This was the orangeish-red one -- I moved it near the other two, and it's turned more red, with all the heads much more inflated (gone from perhaps nickel sized to quarter-to-fifty scent piece sized).
 
I am having same issue. Have several Acans with every color you could imagine in them. Several weeks later, they are all blue and yellow/orange in color but appear happy otherwise.

I am using Sol Blue AI's
 
Is it an actual shift in color? Or is it a wash out in color due to some missing wave lengths not emitted by cool white and blue led's for instance yellow/green/red areas?

I'm making my own led fixture as of right now and I'd heard of people saying their colors had washed out, I thought it was just a lack of certain wavelengths. IE you can't have a red object if it can't reflect that wavelength of light.

Personally I am using a mix of royal blue, cool white, warm white, and I'm debating on red.

50% royal blue 25% cool white 25% warm white and perhaps 12 red sprinkled through out with no lens.

All of which are on their own independently dimmable strands.

Any thoughts?
 
Just another possibility, could it be linked to uv radiation? If im not mistaken isn't one purpose of corals colorant to block uv, kind of like a tan. Uv isn't put off by most led's like some of the metal halides.
 
Mine was an actual shift in colors because they had their original colors for a few weeks under the same LEDs and then the colors changed. I am not ruling out that there is a possibility that water conditions may have caused mine and I will be checking a few extra parameters soon (e.g., K and Iodine)
 
That is very interesting. I recently bought a Aussie Gold Torch from my friend. The torch was super orange under his LED, but it is a kind of bleached under 250W MH now at my tank while my acans and brain colors are so colorful.
 
I think the answer maybe what a few posters put above. One definitely is the color spectrum of the LEDs that you have. So many different areas of the color spectrum are missing when you only have white and blue.
Secondly I agree with the above poster with the uv thought. Like he said the reason they color up so much is because they are protecting themselves from uv.
