Salt in the Aquarium
I have seen a lot of cases recently of advice being given to add Salt to Freshwater Aquariums. This has been given for various reasons, including as a remedy for illness.
But it seems that some fishkeepers are adding Salt to healthy freshwater Aquariums.
Aquarium Salt is often found for sale in Aquarium stores, and it is ultimately no different to the Salt you use on your dinner.
But Freshwater fish are not accustomed to Salt, in fact, in Freshwater rivers, there is very little to no Salt content at all. This means that many freshwater fish do not tolerate Salt in the Aquarium.
