using salt = bad???

Yeah, if you put dump out your salt in your fish tank, of course it will kill them. In moderation and recommended amounts, it can be very useful. Keep in mind some fish tolerate salt better/worse than others.

What is this anti-salt propaganda?

**In the ocean, fish will swim into freshwater to rid themselves of parasites, and then swim back into the ocean. The fish do this only for a few minutes, and then return to their natural environment. The reason that the parasites fall off is due to increased osmotic pressure. When you put a marine fish into freshwater, it is like putting a heavy weight on top of the fish. So, this does not mean that this will work for freshwater fish the same way... in fact it will not work, due to the fact that you are putting fish into an environment with a much lighter amount of osmotic pressure.

so when fish are sick we should be using RO/DI water instead?

your a genius mgk, also very handsome .

of course that would make it harder on the fish and may cause deficiencies in the long run, but it may be more effective in killing the parasites then salt.

as adding salt only creates a hypertonic, causing cells to shrink(which i would think is non-fatal but stressful). where as a hypotonic(no dissolved solutes) environment causes cells to expand and possible pop.
of course this leaves the question effective freshwater parasites are at regulating osmotic pressure in both environments.

A good way to test the salt theory, would be to set up 2 aquariums.

1.) Salt one aquarium (tank 1) according to the instructions that were given to you and use a dechlorinator, if you are using tap water.

2.) In (tank 2), use a nitrifying bacteria like our Aqua Gold, and a good dechlorinator for your tap water. Do not add any salt to this tank.

how the hell is that a test about the effective-ness of salt on pathogens?

all the fish would die or be stressed because the one tank is not cycled.
the key to a good experiment is only changing one variable.
