DIY sea salt mix?

[DeepWat3r]

I'm planning on setting up a sizeable fish-only system and wondering if it is possible to make a DIY sea salt mix using the same idea ESV salt mix has? Using good-grade magnesium sulfate and sodium chloride as the bulk of the mix and adding on aftermarket additives we have available to round it out specifically just in terms of a fish-only system? Or is it remotely possible to use commercially available salt mixes and add magnesium sulfate and sodium chloride to it as a way to increase the volume of salt water it can produce (50/50 mix?)?

The system is gonna comprise of 4-5 100-gallon aquariums that will house a variety of fishes like fairy wrasses, anthias, and a plethora of angelfishes.

Sure it's possible, the ingrediants shouldn't be hard to source. Back in the 50s and 60s before Instant Ocean showed up there were several fomulas floating around for making salt mixes. FOr 500 gallons it seems to me it would be easier to just buy a salt mix like Fritz Pro blue box. Measuring and mixing the ingrediants and maintaining a consitant quality seems to me it's more work than it would be worth for that volume of water.

I give a recipe for the major ions here, which may be adequate for fish;

How long are you wanting to store it for?

I would not add any anti caking agents.

Depending on how well is is sealed, it should be OK for 3 months, but if the materials have extra moisture in them to being with,

Try a bag of silica gel desiccant inside the container, may absorb the moisture before the salt.
Use a nylon bag or sock.
