- A compact current hang-on option when the aquarium is within Fluval's 5–20 US gallon interval and its rim and rear position satisfy the manual limits.
Tradeoffs to weigh
- The listed maximum flow and tank range do not establish stocking capacity; the box still needs a compatible rim and measured rear clearance, and no media-basket volume is published in the reviewed table.
