SPS dying

Looks to be from high nutrients IMO as well. Couple decent WC can go a long way

This looks more like high nutrients and high organics. I think a mixture of aggressive gac and purigen would take care of the organics and possibly cutting back on coral foods.

What makes you think it has high nutrients, if it's the red turf algae that showed up during a phosphate spike back in decDecem and it just hasn't gone, I haven't stressed since I'm upgrading soon with new rock

I do about a 25% every two weeks, was doing more often but disntd see an improvement

You said your po4 was 0.15 and the fact you said you were having a hard time reducing po4 with gfo, couple that with your feeding regime and the pictures, everything points to high nutrients. Not sure how that could be argued?

Until I dosed NO3 my nitrates were .25 and that was about a month ago I cut out the product that caused a phos spike. As far as more specifics for feeding I only do 4ml of the erergy, feed only what they eat of strained food, and 1/2 tsp of Roids 2 times weekly, if I don't maintain my NO3 it would drop to virtually zero in a week

As I stated it looks worse from the spike I had a while back but it hasn't grown it actually is slowly getting better, if your talking about the turf algae being why it looks high nutrient

Alk can make a coral stn so bad, I always had issues with acros they would be fine for a month and then boom stn but that was because I was running high alk 11.2 and now I’m lowering it I also had high po4 about the same as you and couldn’t get it lower with gfo but now is lower with nopox. I also had better luck with larger pecies and not numbs.

 

[Camaro Show Corals]

So keep your alk at 8.2 and calc at 450, I know some guys ran there mag a little high about 1450 and they had better luck

I want to help you through this. This tank can turn around but if any advice given is going to be an issue then i'll have to back off. I just think there are too many elements at play here. If this were a low nutrient tank, then adding aminos, coral foods, carbon dosing would work. But I'm just not seeing it work here. Unless you are happy with algae growing on coral skeleton, then keep doing what you are doing. Otherwise, go back to the basics. Maintain water changes, don't broadcast feed, back off of coral foods, reduce the carbon dosing, don't mess with the lights, just stick with stability.

I'm not trying to knock any idea just asking a question to why you thought something sorry if I came off the wrong way

Since it is no longer low nutrient like it was I will cut out coral food and see how it does, as far as rock the reason I am not stressing is I'm going to be breaking the tank down soon anyways the main purpose of this post is to save what SPS I have for the transfer I should have specified that

No worries. If by any chance you have remaining sps after the new build is ready, clipping the dead areas off will allow the sps corals to regrow. In fact it will be easier for them to regenerate those clipped areas as opposed to dead skeleton with algae absorbing available nutrients. In the mean time, reducing organics and maintaining water quality should be the focus.

Yeah I've been clipping the dead stalks periodically I need to do another trim

Maybe wait till you transfer them? Let them regen in the new tank?

Some SPS seem to be sensitive to palytoxin, especially Seriatopora.
