I don't have any experience with those salts but that does seem really high if you've done larger water changes with that salt already ? Have you tested the calcium out of a fresh batch of saltwater from those salts to see what the calc is from NSW out of those buckets? Maybe it's an unusually high batch ? In other words, if you test out the calc from newly made saltwater from those buckets and find the calc to be high then ya, doing larger water changes with that salt isn't really going to lower your calc at all! You'll need to find a lower calcium salt.
