A sump is a separate container, usually sitting below your display tank, where filtration gear lives and increased water volume gets added to the whole aquarium system. You see them most in saltwater and reef tanks because stability matters a lot there. Below is a practical breakdown of how aquarium sumps work, why reef keepers use them, and what parts matter before you set one up. It should help you understand the plumbing, avoid messy surprises, and keep your tank cleaner.
