    Hello I am new to marine aquariums I just have 1 question for now. I have a guage on the side of my aquarium to measure my salt levels. When I originally started the aquarium the level was reading 1.024. As as I leave it I notice the level slowly drops currently its reading around 1.021 -1.022. Should I leave it? Add salt? Thanks in advance!

    If you are topping off with fresh water each day simply wait a couple days or turn off the automated top off/ATO if you have one.

    Personally I have never seen a gauge that provides SG values built into the aquarium. To be sure of this gauges accuracy get a hydrometer or better yet a refractometer to double check values.

    Basically I would not intervene until you have verified the value against a second measurement instrument.

    Welcome to 3reef. :)

    My tank is only a 15 gallon tower aquarium so i do not have an automated top off.

    How long has this tank been running, are there any fish or corals in the tank?

    I started it up last friday. No fish or coral. I have rock. I bought 8 small hermit crabs and a peppermint shrimp. All which seem to be doing well

    Ok then, let evaporation happen and you'll see a rise in the SG.

    If the shrimp or crabs begin to look stressed, top off with saltwater for a day or two.

    Water does evaporate on all tanks, salt does not. The tank's specific gravity will drift up as fresh water evaporates, leaving salt to become more concentrated.

    In the future think about getting a second hydrometer to match values against. A refractometer or probe however are your best options in the long run.

    Anything that stays in the tank can get salt built up on its sensor and make it useless. I'd personally look into getting a refractometer - they're like $25 on ebay. Hydrometers also can have accuracy problems and really aren't much cheaper (at least with the ebay route).

    Edit: Also, I'm not sure what you meant but even if it were low, you should never add salt to your aquarium that hasn't been mixed in water yet. You'd regret the mess.
