From ChoanoWiki

1L 70% natural seawater

5g tryptone

0.1g yeast extract

0.1g FePO₄ ^{[<cite_link_label_group->]}

15g Agar

Notes

1. ↑ Iron Citrate will dissolve fairly easily [few hours whilst stirring] , FePO₄ seems to be soluble to only ~40mg/L in seawater and results in a large clumps of precipitate on the plates. Iron Citrate may precipitate over time, though.
