The sump is the center of all complete saltwater filter systems.

Filter pad or a filter sock trap waste from the water entering the sump.

We recommend purchasing the largest sump that will fit in your aquarium stand.

Having extra space in your aquarium sump makes it easy to upgrade your aquarium system in the future.

Filter systems using in-sump protein skimmers and/ or submersible pumps require larger sumps than systems with in-line (external) pumps and hang-on or in-line protein skimmers.

You can place pieces of live rock in the sump to act as additional biological filters.

It is always better to have extra space in your aquarium sump than not enough.

Your sump must be able to hold any water that would drain from your aquarium if your power shut off.
