What role does salt play in ornamental fish keeping

Adding salt to an aquarium refers to coarse salt, not ordinary household seasoning salt. The reason is that ordinary household salt has been processed and is said to contain no nutrients, while coarse salt is unprocessed salt and contains many rich trace elements. However, coarse salt added to freshwater does not equal real seawater (for the reason, just check the major marine fish keeping websites and you will know), which is to say its trace elements are not completely equal to the content in seawater either, but for those of us who keep fish with tap water, it is at least the simplest and cheapest method! A bottle of trace elements sold on the market, with no idea what the heck is inside, costs 500 yuan.

Salt is a panacea - this saying may be an exaggeration, but it cannot be denied that it is indeed useful and effective. Generally speaking, if a fish gets sick, first check that the water quality is fine, then add a bit of coarse salt and it helps. Even more so, for early-stage dropsy, early-stage cloudy eyes in fish, or skin diseases and other common illnesses, adding coarse salt usually brings improvement, and it is much more reassuring than casually dosing yellow medicine. There are even cases where adding coarse salt to some strange and bizarre diseases unexpectedly cured them too. Moreover, coarse salt is not a drug and has no aftereffects like antibiotics, so it is truly an essential good remedy for fish keepers.
