Mix reef and salinity .

Question I'm trying to found out is what level is my salinity supposed to be at? Yes I have mix tank. The level is at 1.25SG

 

[Rmckoy]

1.025-1.026 ( 35ppt )

1.025-1.026 ( 35ppt )

Thank you see some people have it at 1.027. Some say it good and other say it too high.

The acceptable range is somewhere from 1.023-1.027

stability is key !
maintain the same salinity not to fluctuate too much

Mine have always been 1.025 at 77-79 degrees

Got it thank you

It's an interesting question in my opinion. The standard answer is 1.026, that's what probably 80% or more of reefers are doing. However, in nature ocean salinity varies quite a bit. Many parts of the Red Sea are consistently at 1.030 or even a little higher. I have dived the Gulf of Aqaba and I can say it is an absolutely gorgeous reef absolutely jam packed with life and many of the stony corals we keep in the hobby.

Whether the corals are flourishing in spite of the high salinity or because of it I don't know. But I think running higher salinity would be a very interesting experiment although not recommended if you don't want to take a risk.

I think if properly acclimated over time .
and possibly even select the species from that higher salinity location it would thrive .

I’ve always questioned if someone were to do a geographic reef based on specific locations .

So all Red Sea species ,
All Australian , all indo . Etc

This got me a little more interested in the topic and I found this paper: https://bio.biologists.org/content/biolopen/6/12/1943.full.pdf

Long story short, Aptasia acclimated to 42PSU (1.0316SG) experienced less bleaching and more photosynthetic activity when heat shocked than lower salinities.
