I accidentally placed an order for Seachem Marine Salt instead of Reef Salt when I made my big equipment and supplies order last week. Its already in route so too late to change. I got 2 containers of 160g worth of salt, thinking it would cover at least the first few months for my 90g. I haven't even cured my live rock yet or cycled my tank, so will have to go through a few water changes at least during that process, but will probably still be using up the marine salts when I start putting livestock in my tank. Is this a big deal? I would like to add a few corals near the beginning, but if I just do soft corals to start with, will they be okay with the marine salt instead of reef salt? Or should I wait to add any corals until I've used up the marine salt? Thanks! PS - first shipment of dry rock arrives today - so excited!!
