ok so i am setting up a brackish tank but i need some help with setup. what should i use for substrate? i was thinking refugium mud or should i just use plain sand? also how many tablespoons of salt per gallon to get the 1.008 i want to achieve for the fish i am getting(i will not say what species) also i need to use marine salt and not the reef salt right? and can i grow mangroves in a 10 gallon or do a need a bigger tank? and just using a plant light for the tank if i want to do mangroves? and whrere can i get mangroves? thnx. i was gonna do a piece of driftwood as the center piece and wanted to do row of mangroves in th background, its only a 10 btw. thnx
