Explore this buying guide ↗Why consider this model?
- Compare U2 for an in-tank fit in its published interval when the 8-inch body, 5-W draw, media format and adjustable output suit the plan.
Tradeoffs to weigh
- The 105-GPH label is pump output, not a measured aquarium circulation result; it occupies more tank wall than U1.
