Why the hell do my sps keep dying

[dabandit]

I've been keeping fish and softies for a loooong time so by no means am I new to this. My water parameters are 100% perfect,i've dumped thousands into equipment to rectify this with no luck. What gives? every piece of sps ive ever put in my system has died within 2weeks,the polyps are fully extended and colors are beautiful then the next day im left with no more than a skeleton. Could I have a parasite or bacteria and what can I use to fix it if I do? I've started dosing with coral snow yesterday because I was told it would break down possible harmfull acids,aside from that I just dose the usual suplements. I keep beautiful fish and used to keep beautiful softies in the same system and never had a problem with anything other than sps.....all species of sps. PLEASE IM DESPERATE I have too much into this to walk away now

no disrespect but '100% perfect water' doesnt tell us much. we need to know

CA
mg
po4
no3
alk
salinity
temp
what type of test kits are you using

those stats would be a good start. then we need to know all your equipment
that you are using. what size tank is it? what type and size of softies do you have? if the tank is too small and your softies are large they may be attacking your sps if they are in close proximity. i would quit dosing until you know exactly where your water parameters are. sps are not impossible to keep, they are just picky sometimes.

What is your mag at? And do you still have softies in the tank and if so are you running carbon?

water parameters would help. system info like lighting, filtration, what you dose and if you test for it etc etc. just the fact that they're kicking the bucket isn't enough for us to help in any way.

Ok but im sure you allready know what good parameters are but here we go...
75gal single overflow,35gal sump inlet baffle and outlet baffle stuffed with lr pieces,euroreef 120,phosban,phosban with carbon,2x250mh with 2 96wpc,2 koralia 1's,nano koralia,115lbs lr,deep sand bed....thats my equip

Livestock is naso,ocelaris,green spot dragonet +cuc

Parameters are phos.0,nitrate0,nitrite0,ammonia0,cal450,ph8?it was right,temp82,sal1.022,alk10dkh and I've never tested for mag.

[dabandit]

I dose trace elements,cal,phyto and zeo

[dabandit]

test kit is professional grade test tube style

[dabandit]

I've never had to dose for ka my water changes keep that in check 10% every3 weeks with instant ocean

I can't seeing the Low ORP if he has a over flow and the water is travelling down any huge water movement the orp is going to be up some what. I can't see that the
alk is that bad lots of Reactors are pumping out 10-11 DKH out for reactors. HOw are the SPS dying in the tank are they dying from the top down or the bottom up.... so you have any nudibranches in your tank that you dont know about that are eating the SPS

The first thing that jumped out at me was the lower specific gravity, but it sounds like this would be something more devastating.

Have you tested for copper?
