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

  1. Rack Member Member

    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.

    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?
