Many hobbyists keeping fish only used water with less salt content for one reason or another, but the same hobbyists kept the s.g. at 1.026 for their reef tank because it was better for the inverts and corals.
Based on my years of reading the forums on RC, I believe that the majority of hobbyists are using at least 1.025 - 1.026.

Ahh, maybe I should raise my Sg a little then, since I started FOWLR and now trying to keep corals. hence Trying!!! LOL

Just be sure to make the change gradual.
Perhaps just add water mixed at 1.028 instead of your normal top up water (to replace evaporation) until the level comes up to where you choose to keep it.
That being said, there are many who keep their reef tanks at 1.024. Obviously you do need to boost the calcium and magnesium if you want NSW levels for those elements, but not wanting the NSW s.g. level.
With FOWLR, changes to salinity still need to make made gradually in an upwards direction, but can be made rapidly in the downward direction because of the way osmoregulation works with fish.

I keep my reef tank @1.026 now using IO reef crystals and have notice that my coral's & livstock seem to like it better. My FOWLR is @1.024 using just the IO salt.
