    Hi all.

    This may be a really noob or dumb question, but I just want to make sure that I cover all the bases.
    When I fill my new setup and need to start calculating quantities for ferts, etc. , do I only use the actual volume that I used to fill the tank?

    Example (hypothetical):
    My tank is 69L
    The substrate, hardscape, etc. takes up 12L
    The cannister can hold 3L
    So, therefore I would fill the tank with 69-12+3=60L

    When basing my volume calculations, do I use 72L, 69L, 60L or 57L?

    Sorry if this is a stupid question. :iamwithstupid:

    TIA

    I would say actual water volume will be your best bet. Makes more sense.

    if you want to be spot on then yeah 69-12+3-filter media would probably be the best formula, but you dont have to be that precise..
