Inverts and salinity

[RaymondL]

I'm told my multiple sources that 1.026 - 35ppt is high for inverts, and 1.025 is more ideal - I don't agree with this and don't see why this would be an issue. Can anyone vouch for this?

I aim for 35 PPT in my large tank with no issues. Inverts are happy and thriving (.. as far as I can see at least; i haven't asked them! )

I suspect some inverts might me more fragile and susceptible to high salinity than others- but that's out of my expertise!>

The difference is negligible.
I know a guy who kept everything @ .022 for a reason that escapes me and his tanks were gorgeous too.

35 ppt is not high for inverts. and - its a very very small issue either way - 1.025 or 1.026 is fine

There’s no evidence that lower salinity than the ocean average is preferable.

So long as it's stable, a normal reef tank range will be fine. Some inverts can tolerate some degree of salinity swing, but there are some that can be very sensitive to it, and as it's not something many aquarists run into, it's not necessarily well documented as to which are least tolerant of it. I've always kept mine at 35 ppt and that has worked well for everything so far, and I've probably kept more kinds of shrimp, crabs, and mollusks than most.

I think the only risk would be inverts that were being kept in really low salinity and are suddenly/immediately dumped into much higher salinity. (1.025 to 1.026 doesn't really qualify here, though)

Inverts depending on which one - may tolerate low salinity more poorly...
