I've also heard that you don't want to use a water softener for aquarium water, but have never dug into the reason why. I'm guessing it has to do with a buildup of salts that are not balanced like seawater. But I've never heard of it messing with calcium levels.
Agree with what cCccccapt said earlier... your salt is known for high calcium - even using RO
water - so if you're not wanting that high of a level then the only thing you can do is switch salts. (Or mix to a lower salinity, but I don't think you want to do that!
