I was just wondering why brackish is usually considered as closer to freshwater than marine in respect to setup and such. Brackish could have high salinity, like 1.18 SG, and it's made with marine salt instead of aquarium salt, so I was a bit confused as to why all of the special equipment usually recommended for saltwater is never used in brackish.

Most of that equipment is there to deal with stuff from the live rock or the fragile nature of many marine species. A brackish tank really only needs a filter (preferably one that says "for fresh or marine") because most brackish fish are pretty hardy, don't need ultra-specific salinity (in fact, it's better for most of them if it ranges periodically), and there's nothing in the tank producing a ton of extra waste protein like live rock does.

Great! That answers my question perfectly! Thanks Sirdarksol!
