Infishkeeping, asump is an accessoryaquarium tank in which mechanical equipment is kept.[1][2] A remote sump allows for a clutter-free display tank.
It is found mainly in areef aquarium ormarine aquarium. The sump sits below the main tank, and is used as afilter, as well as a holding place for unsightly, miscellaneous equipment such asprotein skimmers,calcium reactors, andheaters. The main advantage of having a sump plumbed into an aquarium is the increase of water volume in the system, making it more stable and less prone to fluctuations ofpH andsalinity, and also mitigating the effects of nutrient buildup or the unintentional introduction of foreign substances. In addition, some sumps have a compartment that can be converted into arefugium, helping to filter out excess nutrients such asnitrates.
A sump can also improve aeration of the water in the aquarium. Water movement between the sump and the display tank helps with gas exchange between the water and air. Increaseddissolved oxygen is beneficial to fish and can also aid in avoidingCyanobacteria outbreaks.[3]
