Standard Reef Salt is formulated around an \"elevated\" calcium and alkalinity reserve without a published mineral assay.

For coral-heavy systems the documented higher Ca and Mg levels plus the vitamin B complex are the trade-off; for a fish-only or lightly stocked tank, standard Reef Salt covers the same salinity at a lower cost per litre.\u003c\/p\u003e","brand":"Aqua Medic","offers":[{"title":"Default Title","offer_id":55285032452387,"sku":"AM30103","price":287.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/13716_Reef_20Salt_20coral.jpg?v=1786066028","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/aqua-medic-reef-salt-coral-20kg-bucket","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
