simple question on Salinity & PPT

[cracker]

So I assume a salinity i\of 1.026 is the same as 35 ppt. Is this true? Thanks

SG changes with temperature. Salinity doesn't.

this calculator follows the prevailing standard of assuming a temperature of 25C/77F.

Yes

Yes,
1.0264 is the specific gravity of saltwater in the ocean as well as the 35 parts per thousand of dissolved salts

In my opinion, any difference from our normal reef tank temps is so negligible that the specific gravity isn’t worth working about...now if you OCD, that’s another story:)

Thanks for the reply's . I'm really not ocd about any part of this salt enevour. As for salt content just needed a base to work from. I have always assumed they were the same just wanted to be sure.

My room is 10 degrees colder than my tank. 10 degrees will throw it off a bit depending on what you read it with and how it's calibrated.
It doesn't matter to my Pinpoint.

Ok checking in . I recently won the Hanna tester give away. The salinity meter wasn't calibrated & my refractometer was way off. So I calibrated the new hanna tester & my refractometer (spelling )
Anyway I tested a new barrel of water & got a 1.025 on the refracto & got a 34.2 on the new meter. Plenty close enough for me !
Thanks Brian
