My tank is at 8dkh currently and I am trying to keep it as stable as possible. It has been up to 11dkh. Since 8 is closer to NSW, I would think it would be better, but my fresh saltwater is measuring 10.5 dkh. Would it be better to shoot for that number so there is no ups and downs or will 20% water changes not really cause too much variations?
