coral losing color

[old 5k0ol]

I got an orange montipora frag that was on the bottom of the stores tank with strong MH lights. I drip acclimated it and placed it near the top of my tank under 216watt t5. The edge is starting to turn white.

parameters:

Ammonia-0
Nitrite-0
Nitrate-0
PH-8.2
Carbonate Hardness-11
Calcium-500
Phosphate-0.5

well its not used to the t5 lights,when you change lighting you need to place on the bottom,it may be water aclimated but it also needs light aclimated as well

 

[old 5k0ol]

any idea what's wrong?

 

[old 5k0ol]

even though its weaker light?

 

[Jr.Ramirez]

You may want to check on how much water flow you have going its way.

 

[Smitty]

I don't think the lights are a problem...especially if the lights are weaker than what they're used to. I personally think it's the phosphates, sps's can't stand them...no corals like them actually.

 

[JustinsReefTank]

Like u said it was at the bottom of tank and may not be used to that much light directly.
Try moving lower in your tank.

 

[old 5k0ol]

I moved it lower. It's about 7 inches off of the bottom of my 75g. And I'll do a small water change. I do have phosban running. Do phosphates leak from old filter fiber?

 

[Northstar24]

Phosphates can leak from old filter media, but they primarily come from fish food. What kind of fish food are you feeding, and how often? Phosphates can also come from tap water. Get yourself a phosphate test and see what your tank is reading, as well as your source water. Are you using tap or RO/DI?

Is it just the very edges that are white? With SPS, new growth will be white. With montis, it's usually the edges, stuff like acros the tips will look white.

Plus high Phos usually browns out SPS. Maybe a pic will help us.

 

[old 5k0ol]

If its pics you want, then pics you shall have.

 

[yote]

Could be starting to bleach or it could be the start of RTN.But I'll admit too,that I can't see the pics good enough to make a decent guess.

 

[reeftanker84]

looks like its dieing to me but hard to tell for sure

 

[old 5k0ol]

o damn

 

[sen5241b]

I've put motipora too close under MHs and watched them bleach and die.

 

[old 5k0ol]

I have moved it down hopefully it turns around.

 

[jzaso]

I agree with Brian growth edge possible

 

[jzaso]

I take that back! just saw pictures not growth edge

 

[old 5k0ol]

it has died.
