Best salinty for a FISH ONLY TANK?

[timdam]

What is the best salinity to run for a fish only tank? Someone told me .017. Would that be beneficial or not? Would it kill off any beneficial bacteria?

I meant 1.017. Is that good or bad?

Really no best without a definition of best from you..
1.020 to 1.026 is a range I'd recommend and 1.025-1.026 would be my "best" target

Agree definition of best is relative..but if you want to mimic great barrier NSW condition then it 1.028 in nature but all of us in this hobby try to shoot for 1.025 -1.026..remember reef does not have only corals it has fish to too...both corals and fish thrive in NSW conditions...

I'm a big fan of natural conditions, but in the artificial constructs of our aquariums, there is a good argument for lower salinity. To survive in salt water, fish have to osmoregulate to prevent their bodies from becoming as salty as the surrounding water. This is work that requires energy. Reducing salinity reduces this workload on the fish. So with all the stresses we put on our pets in these tiny boxes, this is one thing we can do to make their lives a little easier.

The higher the temperature/salinity the less O2 is available in the water. 1.020-23 is what most are kept at.

The best salinity for me would be 1.025-1.026.

I keep mine at 1.025
