    A general rule of thumb on live rock is two pound of rock per a gallon of tank space – however, other things should be taken into account:

    See link:


    Live sand very general rule - 1.5 to 2 pounds of live sand per a gallon of tank space.

    Powerheads will depend on what you stock with.

    As a very general rule of thumb, your powerheads should produce turbulent, non-laminar turnover of at least 10 or even 20-times the volume of your tank. A 100 gallon tank should have minimum total turnover from the combined powerheads of at least 1000 gallons per hour.

    See link:


    I don’t know a lot about protein skimmers but this link was really helpful:


    Not sure what your question is on the Refugium.

    I don’t have any info on sumps – sorry :(
