Hi George,

Good question. It is our belief that fish exert energy on osmosis; extracting freshwater from saltwater to drink, so the reasoning for the lower salinity is to help the fish NOT to overexert it's energy on diffusing the saltwater but to allow it to have as much energy as possible to fight the disease that it is needing to combat.

However, on the opposite side, if the fish is treated in total fresh water for a prolonged period of time it will explode with freshwater in it's system.

So to summarize, 1.018 won't kill the ich but will help the fish reserve it's energy on fighting the parasite as oppose to having to use it's energy desalinating.

Cheers,

Paul
