In need of help from experienced sps keepers!

The fact that you filled your tank full of dry rock and then tried to put the SPS in there is why you're losing them. I've never found tank swaps go well with dry rock, even if you spend weeks prepping it. There is no quick, fast replacement for live rock. Add high phosphate to the equation and you have disaster. Do you have any of your old live rock left? A holding tank? Someone to babysit the SPS?

FWIW, I would also go back to the basics. Put some GFO in there, but don't be too aggressive lowering phosphate either or you might kill your LPS.

1 tablespoon per 50 gallons is a pretty safe dose.

I think I'm just gonna leave everything as is and just do a bunch of 20% water changes back to back if I can. I normally do 20% water changes every week anyways. Yes Myka I kept all my old live rock and sand in a bin in my basement with heater. I'm trying to sell it with my old setup as a package

An immature system and less than optimal water chemistry. Change those characteristics and then see what happens.

Ya, to reiterate what everyone else is saying: Stop. Stop carbon dosing. Stop all/calc dosing.

Just do water changes.

I was helping someone recently who was having similar problems and instantly saw the problem. Pulled all dosing offline and within a week all the SPS were fine. A couple weeks out and they looked great. All tests showed the water beforehand looking fine but I'm 99% sure it was alk swings that were causing it.

Super low nutrients combined with alk swings from dosing is the perfect RTN recipe. If your tank is relatively new, you really shouldn't need to be dosing anything! There's no need to dose alk/calc if things aren't happy (because they ain't growing!) and nutrient levels should be controllable with only water changes and controlled feeding habits (for the first few months at least).

Why didn't you use any of your old rock? Is there algae all over it or pests? If not, I bet your tank would do a lot better with it in the system. As long as there are no pests and it is not cycling (no ammonia), then put it in the sump. If it won't fit in the sump, then put it in the tank even if you're just tucking it in somewhere temporarily. Between that, a few water changes, and stopping dosing I think you'll be back on track.

Ok I will stop carbon dosing immediately when I get Hom. I was told it was to help me raise my bacterial count faster. As I was dosing it from day 1 while tank was cycling. My old rock was removed because they were too big and filled with algae n not too pouris. I actually had way more death with algae than anything else in my old system as it smothered everything to death. Sps LPS and softies. I would like to thank everyone for ur help and input, I appreciate it very much. So for my game plan I'm gonna stop carbon dosing and Mybe slightly increase my rowaphos a bit over time. And of course STOP BUYING SPS lol. Well not gonna quit sps altogether but I will stop getting more for atleast 4-6months as my tank matures. I can't rly stop all dosing as my lvl does drop pretty fast as I do have a lot of corals now but I do notice my cal is always a steady 420 n doesn't change. Mybe I can reduce my cal dosing a bit over time to see if it changes or not

[Myka]

I see no reason to discontinue calcium and alkalinity dosing to maintain levels. Just make sure calcium and alkalinity aren't increasing while the corals are stressed. I would work on getting the magnesium up too. Just quit the carbon dosing.

[jason604]

Ok carbon dosing has been stopped. My Alk is somehow dropping so something must be growing. Cal stayed the same n mag is now increased to 1140. I don't see any sps getting worse. LPS is more puffy.

[Aquattro]

alk will reduce based on acids in the system. The tank produces various acids as part of being and alk is consumed while buffering pH. If Ca is staying constant, nothing is growing (worth worrying about)
