I've been thinking about a few things.
1. When I make RO/DI water I always save some in gallon jugs for top offs. Can I store saltwater I mix up too? Would it be okay in the jug for a week, or will it degrade in some way?
2. Is there some sort of formula to figure out how much I need to top off? Like SG / tank volume = amount of FW to add. I've got a pretty good feel for it by now, but I was just curious.
3. A higher SG is recommended for reef tanks. Is this because they need the higher salt levels, or is it because with more salt comes more of the other minerals in salt mix that they need? Or some other reason?
