With having to refill my Zero Edge recently, I ran out of Salt. In searching I found this new stuff, D-D H2Ocean Magnesium Pro PLUS Salt Mix, and hadn't seen it before.\n\nHas anyone used or heard of it? I went ahead and ordered it even though it was kinda expensive. \n\n[url=http://www.marinedepot.com/D_D_H2Ocean_Magnesium_Pro_PLUS_Salt_Mix_6_6kg_Bucket_Salt_Mix_for_Aquarium_Water-Deltec_D_D_The_Aquarium_Solution-DD2211-FISM-vi.html]D-D H2Ocean Magnesium Pro PLUS Salt Mix[/url]\n\nAlso how much will 23.3kg make gallon wise? Thanks you guys.
