What do I do wrong

[magic_23]

All my corals but some SPS are fine. Some sps corals have burned tips or melt the tissue. I don't know how to drop my parameters:
PH 8.3-8.5
CA 540
Alk 12
Mag 1280
Currently I don't dose anything, how to drop CA and Alk? I tried water changes for 4 weeks now and no luck, is my PH ok when it goes up to 8.5 by end of the day?

Let me guess, Red Sea Coral Pro salt?

What is your salinity at?

 

[magic_23]

Salt seachem reef, salinity 1.025

 

[silent_circle]

Not sure how you would lower calcium but I use muraitic acid to lower my alkalinity

Lol, so quick to blame RedSea. The salt your using has elevated levels, much like coral pro (which I for one have never had any issues in the three years of using it) I find it odd that you could achieve a higher calcium than what is in the salt without dosing. What test kit are you using? I would suggest retesting with another kit or having your LFS do it.

Just got Salifert CA test, exp date is May 2020.

How about my PH is 8.5 ok or too high?

 

[omykiss001]

Any changes to your lighting? Any pics you can provide? That could be helpful as well

 

[magic_23]

No new lights

So first two pic are my new corals from live aquaria, they came last Tue, the pink acro lost almost all the tissue over night. Next to pic are from my display, sometimes the sps will do fine and then some will loose tissue and some are fine and growing. The last pic is my display 180g.

You sure nothing's eating them?

This is in the high end, but I don't think it's detrimental

So she's using another brand of elevated parameter salt. This is the whole problem, her alk is way too high. Unless the vendor you are getting your SPS from is running their tanks at an alk of 12 (they are not), SPS are not going to acclimate to tank that is 4 dkh higher than it should be. Switch your salt to something closer to NSW, I use regular old IO.

Thanks xmas, I think u are right, will go back to regular salt, at least for some time and see what will happen.

Alk is pretty high. Nothing could eat that overnight so it's an acclimation issue. Don't do water changes for a bit, or not as much. Every time you're adding new water you're making your alk higher. The levels should lower eventually as your corals use them up. If you try to chemically change it you'll just get a swing in the other direction.

Izabela,
ALk is high and Ca is high. did you try to change water with lower in alk and ca and High Mag (which will help CA and Alk balance)
you don't dose anything and still like that after waterchange that mean the water you did have high ALK and Ca
Did you run Kalkwasswer on top off if so use RO water only.
if new water come out little low that is good, but not too much drop. let your corals slowly adapt, and alk and ca slowly drop.

Now it totally makes sense, I was wondering why some my sps are fine and some keep dying. Looks like some are able to acclimate to high parameters and some not. I ordered regular instant ocean, will be using it for my wc for some time. I changed water a week ago, will wait 2 weeks before I do another one. Hope that will bring my parameters to normal. Thanks for your help.

NVTE I doesed, Mg, Ca, Alk and kalk but stopped about 6 weeks ago, after checking my water, noticed that Alk and Ca were too high. I keep testing Ca, Mg, and Alk once a week, they are still high. Alk dropped a bit(used to be 13 a week ago) but Ca is still the same.

Mag is little low for me. Try to bump it up to 1350. It will help with the balance of alk and Ca. Sometime it is hard to correct alk and Ca without correct Mag.
