What is the best aquarium filter
? Fish tank filter systems come in various styles to meet different needs. We’ll help you choose the best fish filter
A small fish tank filter
can be a power filter
, a hob filter
(hang on back) with filter cartridges that clean and circulate water. An aquarium canister filter
sits under the aquarium and uses tubes to move water from the tank to the filter. The best canister filter
will move plenty of water and house enough media to support the tank.
The best saltwater aquarium filter is a sump
filter, an extra tank under the main tank that increases water volume, hides the water heater
, and houses powerful filtration
, like a protein skimmer
. Many sumps include a refugium, a small 'refuge' for growing macroalgae, copepods, and beneficial bacteria.
Many aquarists supplement their main water filter
with a media reactor
to remove waste, breed bacteria or control algae.
