New light stress? Loosing colour

[jcosta98]

Hi,

I recently had a frag that changed from an established tank to a pretty new one ( 4 months old). The coral lost much of it's coral , I doubt it is light stress because the new aquarium has a much stronger light , but wanted to hear from you.
Old tank Light : AI Prime HD - Distance from frag - 36cm
Old tank Params:
36 cm
9.0 dKH
3-5 ppm No3
0.046 Po4

New tank Light : GNC Bluray Pro + 2 Actinic bars - Distance from frag 63 cm
New tank Params:

7.3 dKH
3-5 ppm No3
0.046 Po4


Thanks everyone!!


Photos taken under the same light - Right one is 15 days after being changed to the new aquarium , Left one is the first day in the new aquarium

There's a bit of a difference with alkalinity (not sure about salinity?) I'm not clear on the two photos. The new tank has different lighting, but you seem to indicate that both photos are with the same light in both tanks?

I wont blame your lights or parameters , the tank (4 months old) is pretty new and I dont think that its ready for SPS yet .

Hi, salinity remains the same (1.026) , just lower alk on the new one. Yes both pictures are with the light on the new tank , but the first picture is minutes after introducing the frag to this tank so it looks about the same that it looked on the old tank. The right picture is 15 days after migrating the frag from the old tank

Ah, ok - gotcha. Yeah, there's a definite change. The only way to know for certain if you're getting too much light would be to test with a PAR meter.

Too much light would be weird as the coral is at the bottom of the glass, so even if it is getting 400-500 PAR it should be ok ... Can't get a PAR Meter around here .

Also , I have some LPS that I changed at the same time , they are at the same distance as the Acro from the light , some lost a bit of colour , others didn't...

Most definitely the lights. Id raise the nitrates or lower the intensity.

It is probably a combo of new tank, transfer and lighting. Are you sure that the new light is high quality? I have never heard of it... many new lights on the market are not better than the older ones.

@jcosta98

Here is a reference to start with that shows PAR and mounting height along with settings for Blueray Pro's that also includes the bars. Also the Italian forums have a bunch of info on settings. More than likely you are putting down far more PAR than you expect.

GNC BluRay led - first impressions

Hi all! Here is my first thoughts and initial impression of my recently purchased GNC BluRay led and SilverMoon Actinic 590 led bars (these bars come in different lengths). My new nano tank is yet to be filled with water, so cannot yet give more in-depth review. Perhaps I do that later this...

Thank you, yes they are pretty good, very known in europe

@Hydrored Thank you for the reference!! Although those are 2 BluRays , I can kinda get the Idea. I will try cut my whites in 20% and see if it Improves, I'm only afraid of messing it even more! I guess I will give them more 15 days or so to see where it goes. Most of the LPS look completely fine , sitting 15 cm away from the frag , like this ones :
