I found this for you:
Rasmussen et al. (1992) state barium (along with lead and strontium) is compatible with the crystal structure of aragonite (the major form of calcium carbonate in coral skeletons.) One pound is in 50,000 gallons of seawater. Barium concentrations exceeding 1 mg/l can be toxic in marine environments.

I do see that barium is high. Not sure if it is high enough to cause issues. Possibly some metasorb to soak up the barium. Also where would excess barium be coming from??

Metazorb doesnt say it removes barrium
Removes: Aluminum, Cadmium, Cerium, Cobalt, Copper, Dysprosium, Erbium, Europium, Gadolinium, Gold, Holmium, Iron, Lanthanum, Lead, Lutetium, Manganese, Mercury, Neodymium, Nickel, Samarium, Scandium, Selenium, Silver, Terbium, Ytterbium, Yttrium, Zinc.
Id check all your magnets for rust. Rusting screws on pumps. Algae magnets left in the tank. Hose clamps. And pipe clamps (that you attatch to the stand to hold pvc pipe up) also check there is no salt creep that could be falling off of something metal. Check you dont have any metal water pipes avove the tank dripping condensation into the tank.

Hi!
Your Barium levels dont seem problematic! Likely cause is impure supplements or sea salt.
Vanadium is actually well measured by ICP, so i would suggest youre having a Vanadium shortage. - Keep in mind this is an essential trace element. Furthermore your phosphorus level is quite elevated, you should try to bring it down to at least ~0.1 mg/l slowly. I think its a combination of these factors giving you trouble with certain SPS.
Aluminium at 20 µg/l is not problematic and can be found in many tanks.
Best,
Christoph

My Tank Thread
I agree I would not worry about the barium. I've seen folks with much higher levels without apparent issue.

Sorry I thought you meant your tank has high barium

Yeah the high phosphorus could be the issue. I did see that. My red sea pro test shows .08 PO4 but may not be reading accurate. After I did the chemiclean a couple months ago the green hair algae has taken hold. It is a turf velvety type. I assume it is pretty high.
Is it common with high phosphorus to see STN?? I figured it would cause more browning than anything. I am going to do a water change. I have lanthanum chloride which I may try to drive the phosphate down some. I know I don't want zero but lower would be good.

I am using h2ocean salt. I would think the vanadium would be replenished with new salt. I am not aware of a way to supplement this. If you have any ideas let me know.

No, elevated phosphate does not generally cause corals to STN. Some nice tanks have coral thriving at 1 ppm phosphate.

My thoughts exactly. I did not think it caused STN or RTN.
Any thoughts what could be causing the issue @Randy Holmes-Farley
My readings as of yesterday via my test kits
Aquaforest test kits and salifert and red sea pro.
Alk 8.8 aquaforest
Calc 425 aquaforest
Mag 1380 aquaforest
N03 - 5 ppm salifert (probably higher due to alot of green hair algae growth)
PO4 - 0.08 red sea pro
Salinity 1.026 refractometer.
I am kind of drawing at straws. I am going to do a water change tonight 30 gallons to see if things will turn around. Lost an acan frag and the milli is STN and the stylo polyps do not seem to be extending. I will also change out my carbon tonight. (Just running a couple cups in a bag filter in between a baffles in my sump)
Check your alk with a standard 1.135 grams of sodium bicarbonate in 1 gallon of ro/di is 10 dkh. (May not work with hanna checkers)
Also get a multimeter and make sure there is nothing unusual with your electeicity in the water.
One thing i leanred in this hooby and life is never assume!
