New coral dying in a matter of hours.

[Aidanwolf]

Hello I just added a zoanthid and I think it was a Cyphastrea to my 32g Biocube that is almost 2 months old. I temp acclimated them and put them in but the Cyphastrea bleached in the matter of hours and the zoanthids are closed. I did tests with the api saltwater master and reef kit. All the levels look normal.

All the levels looks normal.

What does that mean? What are the actual numbers?

 

[Gareth elliott]

What type of par did you do put the coral in? If too high without light acclimating could cause this. As cyphastrea prefer lower light.

Also pics would help a lot as well as a little basic information about your system. It’s also common for zoas to remain closed for some time after introducing to a new tank.

I'm curious too.

Always post actual numbers as fine can mean a lot of things

 

[KrisReef]

Do you have any other invertebrates living in the tank?

 

[Aidanwolf]

Here are the number for the reef master api results.
Calcium 520
Kh I think 125
Phosphates 0
Nitrate 0.
I did the api saltwater master tests before I got the coral and
There was no nitrates nitrites or ammonia.
The ph was around 8.2 I think.
The Aquarium is a 32g biocube with stock led lights and I do have invertebrates.

 

[Mjrenz]

Your calcium is a little high, do you know the magnesium level?

 

[Gareth elliott]

What salt are you using? That calcium reading seems a bit high for any salt mix i have ever used. Your salinity may be a bit high. Could also be why you have 12.5 dkh.

Also high alkalinity plus low nutrients can lead to coral stress pretty quickly.

+1

Also, from personal experience, ditch the api test kit and go with salifert or something comparable

I just tested the water with a refractometer, and the salinity reads 1.025. I am using coralife salt.

I am eventually going to but I am on a budget.

Is your kh 12.5 or 125ppm?

 

[Aidanwolf]

It 7 drops to reach blue to yellow and that translates to 125ppm.

 

[Mjrenz]

Ok, that should be closer to 7 dkh which isn't too bad. Do you have a magnesium test kit?

 

[Aidanwolf]

Also the temperature is 80F

BTW, almost everyone uses dkh and not ppm here

I going to purchase one.
