Hello when I set up my tank a 45 gal actual water volume about 38-39 gal the salt mix I purchased at the time had a 7dkh 470cal 1350mag. I was surprised that the Dkh was 7 especially when it was advertised as closer to 9dkh… so I investigated and found that this specific brand had a batch go out with low Dkh… fast forward a couple months I got a new box with a Dkh of 8.8. could I do a 5 gal water change with the new salt at 8.8dkh and not hurt my fish?
