Coral Bleaching

[Badger_Reefer]

I went on a 10 days vacay. I have kept a person for my aquarium maintenance. But after back , i have found that my corals have bleached ! How can i recover them ??

 

[Lavey29]

Need better pictures and full tank parameters along with age of the tank. Lights look dark

We need much more information.

Chemistry including alkalinity, calcium, specific gravity?
Are you dosing any products?
Lighting and intensity please?

 

[Badger_Reefer]

Okay. I am giving it.

 

[Badger_Reefer]

My tank is 120 Gallon tank. Its a 4x2x2 feet dimension.

Its been 2 months of set up. Plus i do weekly ammonia , nitrate and phosphate testing.

I have 3 - 60 Watt led light which i run for 10.5 hour period . The blue and royal blue is at 60% max and white is 25%.

Current water parameters-
Salinity - 30 ppt
Ammonia - 0.15 mg/L
Nitrate - 5 mg/L
Phosphate - 0.1
Calcium - 400
Alkalinity - 12
Magnesium - 1170

Plus i run a Chiller Hailea 500 at 25-26 degree celsius

Montipora Digitata and Goniopora

I do not believe they are bleached, it appears they are are dead.

The goniopora for example does not show any flesh inside the skeletal polyps

The montipora had algae growing on the skeleton, and this would not happen on living sections of coral

Can you get closer pics with white lighting?

You're not going to be successful with SPS in a 2 month tank.

Your salinity is way low, alk is to high, magnesium way low. Your tank looks way to dark so I'm guessing your par is way low too. You need to do more research and educate yourself to the hobby.

Okay. I will do more research. But can you help me with the percentage of blue , white and Royal blue channels . And also the photoperiod !! Like what instensity to set ??

Same with goniopora

What brand and model is the 60w lights ?

Should i remove the dead corals from the tank ??

As a general basic guide you want blue and UV at 100% .with whites, red and green at 25%. You want par 300 to 400 top of the tank. 150 to 250 mid tank and 75 to 150 at the bottom.

Yes
