help identify and save my corals please?!?!

[pokegirl1332]

I got a bunch of corals from the wwc live sales most of the ones I ordered are doing great but a few, not so much. I'm still fairly new to corals and I have these in a 120 gallon tank I upgraded to this july. the corals I'm posting came in a frag pack so I'm not entirely sure what they are. Please help me identify and figure out what I can do to save these corals that aren't doing so well. the first image I'm pretty sure is some kind of favite but I could be wrong. it just looks like it's receding and dying. the second is some kind of encrusting coral but not sure what kind looks kinda like it's bleaching so I just moved it a bit further from the light but not sure if that'll help, and the 3rd i think is some kind of green Stylophora, It's hard to see with the white lights on but I can't take a picture under blue lights, I had this one upright in that sand but I think a turbo snail may have knocked it down because one morning it had fallen and had what looked like a white dot, it use to be full and polyps open and healthy and now mostly closed and looks a little like it's falling apart. I don't know why these particular ones are giving me trouble, my other corals are doing fine and I even have a beautiful orange yuma that's been doing great for months now. please help me save these corals.

Favites share a wall while favias have separate walls you're kinda looks like a favia maybe?? As for the crusting coral it could be an encrusting monti or digitata or something else im not sure to be honest, and i think the last one is a stylophora.... anyways i would move them to a shadier region maybe to acclimate to the light... maybe start them out on the sand bed.. but other than that check your calcium alkalinity and PH ect.... try and rule out most of the obvious stuff...

As is mentioned by @Oscar47f we need some info on your system.
ALK
CAL
MAG
Po4
No3
PH
Temp
NSW
Flow as in what kind?
Light?
How long is the tank running?

maybe a favia it's hard to tell really they just look like some other favites I have, I've also had these corals for like 3 weeks now so I've already done the light acclimation and tried moving them around I also tested my calcium, alkalinity, and magnesium today and they're all fairly high. calc i think was 600, mag like 1700, and alk about 13. ph was 7.6 which is a little low, and my nitrates are at 5ppm.

just commented some of my parameters above, and as far as the rest go
it's a 130 gallon tank with
the temp's about 81
for flow I have 2 ecotech mp40's pretty strong
and the lighting is a kessil ap700 again fairly strong at full power.

okay so one more question, how did you acclimate these corals... It could be that those corals were particularly sensitive and needed better acclimation especially if you have very strong lights and flow and such high parameters.. i also recommend slowly raising the ph and letting your other parameters fall to more normal ranges...

my parameters have always been a little high because of water changes before adding my corals, I was using (still am) red sea coral pro salt. I guess I could use kalkwasser to raise the ph a bit. I put them on the sandbed on the right side of the tank with the more sensitive ones further away from the lights and slowly raised the light intensity as I moved them to the frag rack, this being over the course of about 2-3 weeks. I've always aired on the side of caution and taken extra time to acclimate things so I don't stress them too much.

 

[Oscar47f]

I use the same salt but my parameters don't usually spike anywhere close to that.... hmmm kalkwasser will increase your calcium as well so be weary of that, there must be something we are missing here... it sounds like your procedure is very solid in order to ensure acclimation.. do you dip these corals before introduction? and the corals have been on the decline for the entire time you've had them or is it recent???

I hadn't noticed any decline before about a week ago, but since upgrading this tank I had a few months with no corals and frequent water changes, and posted on a forum about by very high levels, but it was also my first time testing them at that point because I've only had corals for about 3 months now. but had this tank for about 7 months and my previous 55 gallon for 2 years. some people said it was normal to have the spike because I;m using reef grade salt and had nothing to consume it but so far the levels haven't gone down much at all in the past 3 months after adding corals. the levels have remained constantly high. also what would you recomend to raise the ph then, baking soda or something? thanks for all the help btw :)

calc i think was 600, mag like 1700, and alk about 13. ph was 7.6

All this and your strong light made your corals possible fade away.
Dim light to 50% as we talking KED's here.
Bring down your CAL to 400
ALK to about 9
MAG is good between 1300/1400
What I don't understand is ALK and CAL are very high but PH is reading 7.6 to me that's a red flag.
Would like to know how you tested those three and with what test kit.
What kind of salt are you using?
You must be dosing the ALK/CAL and MAG elements as this is so high.
If you do stop dosing and let it come down.

red sea coral pro mixes up to high alk (11-12) and higher mag at 1400-1500.
I saw the same thing when I used it. I stopped using it for that very reason.

Second pic is mystic sunset montipora
Last pic looks like neon green stylophora

But your tank never takes on the ALK level of your salt that high.
I used red sea pro for two years and my ALK was around 8.5
Due to consumption from corals and coralline algae not to mention that your skimmer is take a small part out as well.
To maintain ALK at 12 you almost had to do a 50% water change every week with small corals
If you have large colonies it's almost impossible.
When I ran a doser I went through one gallon of ALK once a week

most people told me it wasn't dangerous to have the alk, calc, and mag that high and that once I added corals it would go down. I have about 22 smallish frags. but it's never gone down also how can I lower my levels, the salt just keeps replacing them.
also I have the kessils at a lower power, highest is about 40%

 

[pokegirl1332]

for what it's worth the stylo looks a lot better than when I took the pic. and I also have an acro and yuma that are thriving.

For the moment you can use a diferent salt that will be friendly to your corals in lower numbers as Tropic Marin.
