Also I reflexively sometimes wonder why we add sodium chloride to livebearer water (what a Grinch!), there is an advantage in adding a little of a sea salt mix, as is done by Scott Lockwood. That has important trace elements and is buffered towards higher pHs.

To a degree, much cheaper feed salts found at agriculture supply stores will do that too. Those salts are just sun dried sea salt.

Both commercial cichlid salts and marine salts can be expensive. Once you have experimented and found what you need to add to a tank, you can cut your overall cost per unit by whipping together a bucket of DIY cichlid salt or by buying in quantity. Until a friend taught me about feed salt, a couple of my shops provided 10-pound bags of sea salt. Often it wasn't generic, it was simply taken from a really large bag of the stuff and rebagged for hobbyists. Often it is cheaper per pound that way.
