    Hi All

    So I have a question that I would like to know more about and that is tank volume minus other.

    So my tank is 80cm(l) x 65cm(w) x 70(h) and when you put that through the calculator it estimates my tank to be 386L or 102 US gallons.

    If you add the rock to the tank and subtract the glass thickness you have a whole lot less water in your tank and hence my question.

    If your skimmer is rated for a certain volume what volume are they taking about? If you add any supplement to your tank and they refer to x(ml) per L or gallon what is it or have the suppliers taken this into account when recommending dosage?

    What volume do you use?

    Thanks
    Paul

    For dosing you need to take nett volume. For skimming its just easier to go at gross volume.

    and do you include your sump volume in those calculations?

    Yes you do. For the sump you need to only use the volume of water in the sump by taking water level into account and not the actual sump dimensions. Any connected water to the system should be used. For example I have a frag tank connected to I use that volume as well in my calculations.
