Tips for Choosing Aquarium Sump Filters

An aquarium sump filter…

… comes with many advantages for both fresh and saltwater tanks.

This system can:

  • Add water volume to your overall system
  • Provide a larger area for filtration
  • Adapt to your requirements and choice of media

Besides…

… it remains hidden, making your tank more aesthetically pleasing.

When choosing, you should check the following objective criteria:

  • Flow rate: Perhaps the most important thing to consider if you want to keep the water pristine. In broad lines, the aquarium sump’s flow rate should be at least 6 times per hour the size of your tank. For instance, if you have a 10-gallon aquarium, go for a wet-dry filter rated at least 60 gallons per hour.
  • Size: You must also check the water capacity of the sump system; at the very minimum, you want it to be at least 20% the size of the tank. However, the bigger it is, the better. You can never have too large of a sump! You can also use this calculator as a guide.
  • Intake pipes: Most sump filters come with dual intake, although there are exceptions. The dual configuration speeds up the filtration, as the secondary pipe can deal with some of the load. Furthermore, this configuration also helps if the primary system gets clogged, as the secondary pipe can still support your system.
