Well, my 75 gallon tank is here and now I'm ready to set it up. Currently I'm going to be running with an Aqueon Quietflow HOB, but I'm planning a sump on Christmas. However, I'm wondering HOW I'm going to apply the sump to my stand. When add the sump, the tank will most likely already be running and It'll be hard to put a 40 gallon sump in the stand. How do I achieve this without taking down everything or modifying the stand? Could I maybe use a 10 gallon sump?
