I am wondering if there is either a direct or indirect correlation between salinity and the amount of flow needed in a reef tank, i.e., would higher salinity and specific gravity (heavier salt content) require a lower flow as to not “beat the corals to death” with the heavier water?

We are talking differences in the hundredths. While the sensitive animals might notice, I doubt there is a big enough difference in water density to have a noticeable effect on flow. Interesting question though.

There is not any correlation between low flow and high flow and salinity. Keep saltwater aquarium salinity at natural seawater; 1.026. Adjust flow as needed for your tank.
With the range we are dealing with, I agree. However, salt absolutely increases the density of water so I think if we were comparing FW to SW with the same powerhead for instance, I'd expect the FW to have more flow.

Interesting question. I agree with the answers given, but this isn't something I'd thought of before.
