I don't know what specifically is the average, but from what I've researched, this species is found commonly in salt marshes and mangroves as well as reefs, so I imagine it is quite tolerant.
There is one laboratory study that says it can handle anywhere between 1.000 and 1.038.
On another note, I can see the nerites' eating patterns in the brown algal film on the glass. They are already doing a great job!
