Tuck away all your aquarium's bulky accessories with fish sumps available at petco.com. Sumps and sump refugiums can provide a variety of services for your aquarium by helping with filtration, water chemistry, and aesthetics by hiding unsightly accessories.
Aquarium sumps are external reservoirs that connect to your filtration system, drawing water from the aquarium for processing before returning it to the main tank. By adding a sump to your system, you can increase the volume of water that flows through your aquarium. More water means more stable temperature and chemistry.
Fish sumps are versatile containers that can house all sorts of filtration media. Some aquarists use their sump refugiums to hold live rock or other media to grow beneficial bacteria colonies and support biological filtration. Aquarium sumps can also be a great place to install protein skimmers and reactors, keeping your water in good condition and your equipment out of the way. Along with skimmers and reactors, aquarium heaters can also be kept in sumps, making the entire setup ideal for marine and reef aquariums.
