I'm making a ten-gallon sump and I'm going with Fiji cube baffles and I'm wondering how much water would consistently be in the tank id like to know before i buy a cabinet, the main tank is a 40 gallon breeder if that helps
How much water you would consistently have in your sump depends on the height of your dividers I suppose Since you're designing your own sump, you get to decide on the water volume
