I’m trying to decide between these two salts for a mixed reef tank but mostly sps and softies. I like the specs of the pro but prefer a dkh of 8-9. Can I add straight baking soda to my salt mix tank along with the pro salt so that once mixed I get the dkh I’m shooting for? Will it dissolve along with the salt? I plan on keeping in a storage tank and doing a gallon water change per day. Please give me your thoughts. Thank you
