    I don't know if this is the right section, please move it if not.

    I just noticed that my 5 gallon had some pockets of air underneath my sand.
    I got a pair of planting tweezers and poked the area, and the bubbles came floating back up.

    What do I need to do? I heard that these are harmful, and it seems as if my tank is full of them.

    That’s why a lot of people buy MTS. They burrow in the sand disrupting those air pockets. You can just stir up the sand too.

    I'd do a PWC, just in case.
