Man Made saltwater vs. Nature Made saltwater.
Ok, I am curious.
How close to naturally made saltwater can we get??
Say I had a 30 gallon tank, and i wanted to fill it with 'as close to the real thing' as humanly possible, without making an 8 hour drive to any body of 'real' saltwater?
Livestock aside, filtration aside, decorations aside, sand aside, etc etc..
Basically, just water.
What chemicals / elements / nutrients would I have to add, and in what qty's?
Does anyone know?
