What level exactly? I do not trust others to decide what is "dangerous".

While that level is well above normal Co levels in seawater, it is well below the toxic levels shown for marine organisms in this summary by The world Health Organization. That doesn’t mean it isn’t toxic to something, but it the tank isn’t suffering, it may not be.
It might be removed by products like metasorb, but that depends on the actual form Present.

it will take out metals, whether they are high or already in short supply. So the downside is removing things you may want.

Why not just change water? There are many calculators - unless you have a source of cobalt that is leaching from somewhere? The calculators will tell you how many water changes to do - to get the cobalt down xxxx percent. In any case - assuming you're using a good salt - It won't hurt the tank.
