Hi, fellow reefers

Any idea why there white patches?
sorry for fuzzy pic.


dang, how to upload picture?
 
there you are.
it is growing good. just having white patches in the middle of the colony.
it might be burnt by LED?
recently i reduce white 60% to 40%
or due to low nutrients? used to have 0 phos.
no pest observed.
Alk 8, ca 440, mg 1400, ph 8, salinity 1.026, temp 79 been over 1year
using reef crystal salt.(is it cause because this salt has 13 alk)
any ideas?
 
I am colorblind, and I know that doesnt help, but could you get a couple different pictures up? I cannot tell too much detail on where spots are you are talking about.
 
I am having the same issues with my 14"x8" pink Mille colony. I notice that it is only bleaching right under the LED fixture, and outside the fixtures foot print where the par numbers aren't as high it is just fine and growing rapidly. So I reduced the intensity by 30%, we'll see what happens... This particular coral has had a hard time adjusting to LEDs, all of my other Milles and SPS have acclimated to the new light and seems to be loving it.
 
if your nutrient get lower for whatever reason you have to lower the intensity of your leds. I can also be pest, alk swing.
 
This could be unrelated: I had white spots on a digi and did a dip in cold tank water (refrigerated) to do a pest check. I found monti eating nudibranch. The nudi are neat at .1" to 1/8" but do a number on the coral. My control is a coral dip with manual removal of the egg colonies.
 
Right i think lights problem too. I also reduced intesity by35% hope to get healed
Thanks for the comments :)
 
I made them with cree 3w & 5w led myself. Total 48 leds about 200w 18 rb 6 blue & 12 cw 6 nw 6 ww & two t5 54w gissmann blue & purple running around 9 hours!
 
Reporting the process!
after reducing the intensity from 60% to 35% white, 80% to 70% RB for 2weeks,
the pink millie white spots are getting a little pinkish, yay! :)
so the problem was the high led intensity imo.
btw i found another white spot getting bigger at the sunset millie.
i'll post pic later..
 
hi, Nick
blowing for AEFW? no.
I have not seen any of it. Should I?
here is the sunset millie and red circle is white patch.

use a power head to blow coral, if anything flies off, you got AEFW.

also do check for Crabs too ...to me that looks like bite marks from crabs. try looking at the corals with a red light at night,.
 
thanks, allmost
i have some crabs they were coming with other sps colonies, looks like emerald crab
on that millie white spot does not have any bite marks or eggs of AEFW
i have not blown them, i will try tonight.
that white spot still has some polyps and extended. just body color is getting whiter..
and one more thing, front side base has some rtn, the other side base are growing and making new bases, is that ok? means one side dying, one side new growth, weird..
actually, i'm new to sps, so keep learning these spieces..
 
it could be a number of things, just have to go through each and check it off the list.

the growth on one side could be related to flow or lighting, or again pests.

hairy, or black crabs are pests, others are most likely okay.
