too much light? How do you know?

[gusmanda]

What are the signs that an sps is receiving too much light?

[SWINGRRRR]

Bleaching. I think.

[gusmanda]

so if the tips begin to whiten, I should move it down, correct?

[Fitchguy]

It depends on how the tips look. White Tips also are growth.

[scrapz]

just shorten your photo period by 2 hours and raise it back up slowly. problem solved

[gusmanda]

are there other signs? how do you know if it is growth or bleaching?

[scrapz]

do you see polyp extension/coralites forming from the new white tips? If so that new growth.

If it was bleaching, your whole coral would lighten up, not just the tips

+1 for scrapz

[doca]

bleaching shows the coral tissue very "dried", like too much tight to the skeleton...

[gusmanda]

just uploaded a picture, does it look like bleaching or growth?

excellent, thanks everybody!! This is my first SPS so I'm somewhat finicky about it!!

[xxiprxx]

Deff growth on that guy. digis grow like weeds too!

[francis1123]

my first SPS was a purple digi, i thought i was killing it after it started getting white tips in a week.

[elijaher]

growth for sure.

I was about to post same topic, what do you guys think on these ones, too much light?

see orange digi and miami orchid

[scrapz]

digi = growth

miami orchis just needs to color up a bit . Mine has the same white all around it's body

[watson_barrett]

and another.

Bali Tri-color

I use lumen bright reflectors and i'm at about 14" right now (large) 3x400w on 65" x 36" tank. I have a bonsai frag that the body is almost all white and only the polyps are bright green. Under the moolights at night you can see the purple hugh though...(it is right under the center of the LB right now but is almost all the way on the sand bed) Could it still be getting too much light at this depth? Or is it still just adjusting to the lighting. I've only had the frag in the spot for a month or two.

[elijaher]

Not only growth it's a fast growth.

[watson_barrett]

Here is a pic of the bonsai (bottom left)

[D' kingfisher]

i also think its a growth..nice looking corals

[francis1123]

those all look good.

[gusmanda]

anyonw have a picture of a coral bleaching? Just to be able to know what it looks like in the future, just in case.

[francis1123]

i don't have a pic at the moment. but literally the entire coral will fade and eventually turn white. it will still have flesh and polyps extending, just no color.
