Sump Filtration.

[Salman123]

Hey, I'm new here, was wondering should the filter and skimmer in the sump have the capacity to filter the sump, tank above, or both combined. For example, if I have a 20 gallon sump and a 40 gallon tank above should the filter and skimmer be able to filter 20 gallons, 40 gallon, or 60 gallons.

Typically the equipment, any dosing or additives, medications, etc. is based on the ACTUAL total water volume in the system. Even though you have a 40 gallon tank and a 20 gallon sump, you might only have 30 gallons of water in the tank, and 10 gallons in the sump. In this case your total water volume would be 30+10=40 gallons. You would have to take your best guess.

What kind of filter would you be using in a sump ?
