It looks like 0.1 ppm (100 ppb) causes issues for SPS.

Effects of zinc supplementation on growth and colouration of the scleractinian coral Stylophora pistillata

Zinc levels in artificial seawater are often unnaturally elevated, and thus potentially toxic to aquacultured corals. However, our knowledge of how zinc affects corals is still limited. We tested the effects of zinc supplementation (0, 1, 10 and 100 µg L–1) on health, growth, NDVI (a proxy for...

That’s massively over correct level , are you sure you’re not missing a 0 ?

The number is reported as I found it.

There might not be rigorous science behind a recommended trace element level for an aquarium beyond matching it to what’s in the ocean. And if that level is far from the toxic level, that means you have to really screw up dosing to harm the coral. In your case, you might want to search the internet for zinc toxicity in soft coral to see if there are any surprises.

Thanks, illlook into it

I was answering Randy but I think he was asking you

Yes. lol

I wouldn’t worry about the measured zinc level (whether real or test error) unless corals appear to be suffering. I would ensure no metal is in the water.

A few softies are brown on the tips and shriveled up
