    1.021-1.025/6 for a FOWLR. It is not such a big deal if you don't have coral. For a reef I would suggest 1.024-1.026/7. 7 might be a bit high, but natural seawater(far out ocean) is (average) about 1.0265. But it varies quite a bit as you get near the coast. I keep mine at 1.026.

    35 ppt or SG = 1.026

    Reef Aquarium Water Parameters by Randy Holmes-Farley - Reefkeeping.com

    If you're keeping fish only, like was said before, it's not AS big of an issue... Inverts, however have a lower tolerance to changes outside of the norm.

    Corals, especially SPS should be kept as close to 1.026 as possible and have AS LITTLE fluctuation or variance as possible, which means ATO of fresh water is a must and even harder to achieve on smaller systems.

    1.025-1.026 is the typical natural range, but it can go higher in some areas.

    Awesome mine is at 1.026 and I have a 14 gal bio cube. Just wanted to make sure. My box of salt said like 1.023 -.24 and I was just like hmmmmmmmmm I hate when boxes make me question myself!

    I believe that consistency is key... keeping the salinity the same constant number is more important than the number itself.

    What I mean is that if you are at somewhere between 1.024 and 1.027 you're probably within a safe range for most inhabitants. What you don't want to do is have your salinity go up and down as water evaporates or when you make water changes.

    Most salinity checkers whether they are swing-arm, a floating hydrometer, electronic, or even refractometers are not completely accurate... they can be +/- a point in either direction...

    It's better to pick a number, and keep it there.

    Agree. Consistency is the key.
