    What should the SG be?

    This is probably a really simple question that has been asked time and time again....
    What should the Specific Gravity of a reef tank be? This is assuming a tank with coral and fish.

    Thanks!

    My SG is between 1.023 and 1.025 all the time. Don't know if that's the best or not but all of my livestock are doing quite well!

    Why is it called "cargo" when it goes by ship, and "shipment" when it goes by car?

    Yes most people I've talked to strive for a SG around 1.024. Given evaporation and water changes I think the range Piatchie mentions is reasonable. The real key (just like temp) is to avoid any quick swings in the SG.
