yes... because the salt mixes we as reefers buy like instant ocean, reef crystals, red sea and others have the calcium and other trace elements it takes to raise the ph making the end salt water alkaline as opposed to acidic or neutral
if you have the proper alkalinity and ph readings chances are you may have a problem with low oxygen levels... because carbon dioxide lowers the ph in water
Thanks, I've never had a pH problem with my saltwater tanks, but I have with my freshwater tanks, and never really knew why.
