Stylophora turning white....

[Dan13]

Hey guys,

Had my Stylophora for about 5-6 weeks now and it has started to turn white over the last 2 weeks.



Some details about my tank....

Ammonia 0
Nitrite 0
Nitrate 20
Magnesium 1400
Calcium 440
Phosphate 0.1
pH 8.2
DKh 10
Salinity 1.025
Temperature 26.5 Celsius

Tank has been running for around 8 months.

- 95G tank
- 6x 39W Giesemann T5 Lighting
- 3 tunze pumps
- Sump - water enters, goes through bioballs chamber, through to Chaeto chamber, then into large chamber with skimmer and return pump, through a UV steriliser and back into tank
- 15% water change every two weeks
- Dose with Microbe-Lift All In One trace elements
- Feed coral with Microbe-Lift Coral Food Plus every 2-3 days
- Feed fish a mix of Formula One flakes and Mysis

Inhabitants....

1 Ocellaris Clownfish
1 Blue Tang
1 Sleeper Banded Goby
1 Bi Color Blenny
3 Yellowtail Damselfish
2 Peppermint Shrimp
2 Scarlet Cleaner Shrimp
1 Blood Red Fire Shrimp
1 Blue Tuxedo Urchin
1 Orange Collector Urchin
8 Mini Zebra Hermit Crab
5 Turban Snail

Frogspawn
Green Leather Mushroom
Red Montipora Digitata
Red Montipora Capricornis
Blue Tip Acropora
Radioactive Dragoneye Zoanthids
Pink Hystrix
Pink Gorgonian
Pink Anthelia
Pulsing Xenia

The Stylophora (as well as the other thriving corals) were placed on the sandbed for 2 weeks after acclimating, was full of colour and slowly moved up the tank to where I wanted it. It is about 8 inches from the surface of the water, with the lighting another 4 inches above the water line. So 12 inches from the light. It has a medium flow (when the polyps were out fully you would see them blowing a bit, but not crazy flow.

I don’t think I have missed out many details, but if I have then just ask me.

If anyone has any hints or tips on this it would be greatly appreciated.

Cheers.

Hi
Your coral has stn. How are your other sps?
Same problem?

 

[Dan13]

Pink Hystrix is slightly losing tissue as well. Not as bad as the Stylophora, but still a bit.

All other coral are looking great. Can send pics of all corals if wanted/needed?

Anything I can do here?

 

[eraser2001]

I saw also that you have your alkalinity at 10 sky, but How was it in the last 2 week?
Always 10 or Did you hev some variation ?

 

[Dan13]

Alkalinity hasn’t shifted since I’ve had any of my coral. I run my water tests 1-2 times a week.

 

[BoomCorals]

I would test alk more frequently and I’d also slowly lower alk to 7 or 8. Also stop dosing the trace elements since you are doing water changes. You may have over dosed trace elements. That and the alk are the two things that jump out to me.

 

[Dan13]

Ok, how do I lower my alkalinity? I have powder to raise it if needed, but do not know how to lower it.

The trace elements I was told would help my coral grow contains elements such as strontium.

Will lowering the alkalinity stop the STN? Is the coral lost already? Any way of saving it? Will it recover on its own?

Something that sticks out to me is the peppermint shrimp.I have one banned that was stripping any sps with small pedals like stylo and monti digitata.just check em and watch at lights out

He lives in the sump now with other bad decisions like a giant 14" fish catching brittle star and anything that has crab in its title

I do have a feeling that it is something within my tank that is doing it. The reason I had originally ruled out STN and RTN was because the flesh is disappearing in random places. It is not stemming from the base or the tips.

If it is my peppermints (I had them destroy an anemone before by taking pieces out of its foot), how do I remove them from my display tank? They hide all day, only come out at night, and are so dang quick!

If it is my shrimp and I remove them, is there a chance of the Stylophora growing back?
