Coral frustrations

[Ogi]

I keep a stable tank dosing every single day and my parameters stay in check, 450 calcium, 1350 magnesium, 9 dkh, 0 nitrate, 1.026 salinity tests are done weekly using red sea pro test kits and water changes are done weekly of 20% using redsea coral pro salt. Here is my question, is it normal out of my 30+ corals, two have issues =( is it normal? are they just a weak specimen?? i dip all my corals and have others off the same species in the same spot doing fantastic.

You might want to let the nitrates drift up a tiny bit. I've always had best color with about 3-5 in nitrates

sorry, i forgot to finish that figure 0-2ppm is what i mean't to say, because its just the slightest amount of pink showing up.

Your salinity is kinda high..what corals do you have? From my experience, 1.024 is a better level.

LPS, SPS, Leather, out of the 3 torches i have, one is looking super unhappy.

Try to lower your salinity slowly to 1.024...

When the water evaporates, your salinity goes beyond 1.026. That could stress your corals..

I have an ato, my water never changes past 1026, i'll try lowering the salinty to 1025

It could be that the particular corals in question do not like the flow or lighting in their current position. Also, since you are running a mixed reef chemical warfare on the corals part could be playing a role. Do you run Carbon?

i'm not believing this at all, 1.026 is just fine, 1.024 is a bit low.

X2 to what Mark9 said.

I would shoot for 5 nitrates as even SPS need them, but in the case of your torch not being happy I'd say it's because your nitrates are too low. As I call this your water is too clean.

There is a thread in the advanced forum about adding nitrates, it would be worth your time to do a search for it.

Phosphates play a role as well. I found out the hard way that 0 NO3 and 0 PO4 is not the holy grail that some suggest.

Zooxanthellae require some nutrients and if they're not happy, neither are the hosts.

Interestingly, different frags of the same coral reacted differently to the same environment. One lost 85% of it's polyps, another lost 20% and a third lost nothing but stopped growing.

What are the 2 corals that are not doing well? They may not like where you placed them. You could try moving them to a new spot ans see if that works before you change anything else.

 

[Ogi]

Yes I do run carbon, the corals not doing well are a torch coral which has two torches other torches next to it growing rapidly, though I have a elegance coral that could be at war with it and the second is a fungia, which did fine for months but I can see skeleton today. Also I've introduced a green clown goby today, I'll raise my nitrates to 5 see how it goes.

20% weekly water change is overkill, but its your wallet not mine.

 

[Percula9]

I agree that coral warfare might be an issue.I wouldn't change the salinity.Water to clean is not always good.Reduce the frequency of your water changes.You can try moving the corals that are not doing well.

 

[ReefsandGeeks]

+1 to moving the coral. If you have 3 coral that are identical, than the ones that are doing bad most likely either don't like the light, or the flow where they are at. If you really love where they are, you could try adjusting your powerheads, but that could cause issues with other corals not liking the new setup. I've gone this route, which has worked for me, but only after many hours of tweeking to get everything just right for all of the coral. Sounds like your parameters are all in check to me.

Any way you could post a few pictures. That could help come up with some suggestions as where to move them.
