Is 7 Pound Of Substrate Enough For A 15 Gallon Tank?

    I'm going low tech. Was wondering if this is enough. Plants such as:
    Anubias
    Anacharis
    Rotala indica
    Hygrophila difformis
    Cryptocoryne

    Not sure how accurate is the 1 pound per gallon rule.

    It does depend on the design of the tank, one with a small footprint but tall will take less than a long, short tank, but in general 1 to 2 pounds per gallon will give enough depth to anchor plants.

    It'd work, but it'd be pretty thin. I'd do more than that, personally.

    This is 20 lbs of Carib Sea ECO Complete in a Fluval Flex 15. I don't think 7 lbs would be enough for a planted tank.

    Make sure it is at least 2-3 inches high.

    And if I supplement it with gravel to make up for those extra 8 pounds should work?
