does anyone else do this after a water change? I add doc wellfish's salt after a water chage is it worth it? or is it bullshit to add it? What are the benifits of adding this that you know of? I read on the box reduces stress, improves electrolytes, and improves gill function. I also read it can make fish grow faster. thanks for any replies.

Why would you add salt to a freshwater tank exactly? It's not like the fish just swims in the water and there's an impenetrable barier between itself and the water it swims in, that water is absorbed by your fish through it's skin and swallowed and then excreted in urin to maintain the fish's osmoregulatory balance. When you change the saline content of your water, you're also changing your fish's waste and urinary system since now the water outside of the fish is much more saline and the process of osmosis gets affected.

FRESHwater fish belong in FRESHwater, not salt water. Unless you need salt for a specific ailment, don't put your fish in it.

It kills parasites because they don't have as complex a system as fish for maintaining it's osmotic balance. What happens to the parasites is they literally dry up because the osmotic pressure inside them due to the lower salt content causes the water to flow out from them and into the water. Your fish just has a more complex regulatory system which means it can cope with the salt better, but it doesn't mean it's good for it.

Eltwitcho already stated by view on the matter...

Of course salt works for some parasites, but there's really no need to keep it in tanks 100% of time. IMO keep you tank free of salt until you need it, then up the salt concentration with disease signs show.
