I read a report a while back by someone who did significant testing on those levels in the aquarium. Lots of numbers and chemical jargon. But in the end there were a few points that might help your confidence.
1. Calc above around 420-440 ( I don't remember exact numbers) do not harm corals but don't help either. Coral growth peaks in that range and doesn't get better with added calc. Nor was there any harm with excessive levels EXCEPT on your equipment. Pumps etc will see scaling.
above 12dKh will enhance coral growth even more. There is no maximum dKh
for corals however you will see excessive scaling on the equipment when it gets too high (above 12dKh).
Based on that you are not in a life or death situation with your corals. But you equipment may see excessive scaling. The fact that both numbers are very high indicates you may also have very high Magnesium levels otherwise the carbonates and calc would precipitate out of solution.
If you've recently opened a new bucket of salt i would put the lid on tight and roll it around and flip it over many times to stir it up. I have found that sometimes the salt mixture is not well distributed within the bucket very well.
