A 300 GPH, two-basket external canister. Aqueon's 2025 catalog lists 55–100 gallons, while the current variant page and instructions say up to 75; the finder uses only their conservative 55–75 overlap.

Explore this buying guide ↗Why consider this model?
- The 300 is the two-basket middle variant. Its maker sources disagree on the top of its aquarium-size suitability; a conservative overlap retains only 55–75 US gallons for numeric matching. It may suit a buyer who values a moderate body size and a single polishing return, but the interval is not a stocking recommendation.
Tradeoffs to weigh
- The 2025 catalog's 55–100-gallon range and the product-page/instruction 75-gallon ceiling conflict. The site deliberately uses the narrower intersection rather than choosing a favorable source. Basket litres and high-waste suitability are unknown; gravity-fed placement remains mandatory.
