new SPS in my Tank

[ma3com]

hello everybody

I have 400 L tank
recently I have add new SPS corals I took them from the sea and I put them in my tank and I did light acclimatization
I have LED light
my Ca = 420
Mg = 1240
Kh = 11
Po= 0
NO3 = 0
No2 = 0
Salinity = 1.025

this is the first time have SPS corals in my Tank

my problem is the sps color start to be white in some places and I don't now what I have to do for them I feed them phytoplankton and zooplankton

can you help my in this problem please ??

Welcome to Reef2Reef!

Can you post some pic's of the corals?

If the whiteness is at the tips, it's probably too much light. It could also be too much alkalinity in a low nutrient system.

If they're bleaching at the base, it's probably STN/RTN. It could also be predators/parasites (AEFW, copepods, red bugs, etc).

Pictures would help a lot.

Welcome, u came to the right place to get help. Good luck

Looking at the pictures, I'd say that it's probably burnt tips from alkalinity, but it's hard to tell. Not sure what filtration you're using, but 11 dkH is on the high side if your nutrients are really low.

I'd try to lower your dkH slowly to around 8, which is more in balance and closer to NSW levels. You could also move them lower in the tank just in case it's too much light.

what about this ?

and I want to tell you that this coral was in a low light and today I put them in place have more light and more wave

 

[msderganc]

Hard to tell but that might be predation.

 

[ma3com]

what I have to do now?

 

[msderganc]

I'd lower your alkalinity to 7-8 dkH.

can you see those 2 pic too ??

I think I have two different problem is that right ?

With wild colonies you may have brought some unwanted hitch hikers ( parasites) with them unless you dip. That said wild colonies tend to be more temperamental than ones from captive systems. Your best bet would be to check the parameters (if you can) of the water they were taken from. Try to mimic that to reduce stress and hopefully they will color up and grow.

This is basically what I was saying. Dip with Bayer or Coral Rx and lower your alkalinity to 7-8 dkH (natural seawater level). Randy Holmes-Farley has some good articles on balanced water chemistry.

thank you so much.
all my corals from the red sea because we don't have a lot of imported coral and I don't have any problem with soft and LPS corals, so I want to try the SPS and I know that is a big challenge

how can I make alkalinity 7-8 dkH

thank you and I am so happy to be here in this forum

In order to lower your alkalinity, you need to do water changes with lower alkalinity water. What salt mix are you using? Most of them are pretty high in alkalinity, but something like Instant Ocean has a lower alkalinity level. If you can get NSW (which you probably should be able to, if you got those corals directly), that's probably better/cheaper.

Also, if you're dosing two part or kalkwasser, just reduce the amount that you're dosing.

You don't want to change more than 1 dkH/day, and if it were me, I'd try to stay more towards 0.5 dkH/day just to be safe.

Am I the only one here jealous that you get to pick corals like this out of the ocean? :D

Exactly what I was thinking! lol.

 

[msderganc]

The other thing I was thinking was that it may be helpful to dose amino acids (like Acropower or Reef Energy) and/or other coral foods until you've gotten the alkalinity down. It may help a bit by raising the nutrient level of the water.

I have new test record and I have
Ca = 440
Mg = 1550
KH = 9
