Right now I'm using Kent salt.But started my tank with Oceanic.
I like the calcium level,it was always at 500 right out of the bucket.Alkalinity was a little low for me,9DKH which I would dose SeaChems Reef Builder to bring that up.But only had to dose that once a week.I also found the magnesium to be just a tad low.Sometimes I would dose for that,sometimes I didnt,just depended on my mood at the time.
