Fluval AquaClear A1371 30-Gallon Biomax Filter — 65 g (2.3 oz) BioMax Media, White

Overview

The Fluval AquaClear A1371 30-Gallon Biomax filter arrives in a clean white housing, designed for flexible filtration in mid-sized tanks. This versatile hang-on unit blends mechanical, chemical, and biological filtration into a compact system that can adapt as your aquarium grows.

Why this filter stands out

With up to six times more media volume and the longest water-to-media contact time in its class, this setup supports steady clarity and a stable aquatic environment. A patented re-filtration system lets you slow the flow for gentler circulation without sacrificing filtration efficiency.

• Low-flow option helps protect delicate fish and plants while maintaining filtration performance
• CycleGuard multi-stage filtration targets debris, chemicals, and the beneficial bacterial workforce

Media you can trust

The AquaClear media lineup works together to keep water clean and balanced. The included 65 g (2.3 oz) BioMax media fits the A1371 line and is suitable for freshwater aquariums up to 30 gallons.

• AquaClear Foam Insert traps debris and promotes even water distribution for efficient filtration
• AquaClear Activated Carbon Insert adsorbs impurities with a large surface area
• AquaClear BioMax Insert uses ceramic bio-media to support beneficial bacterial colonies

Real-world use and expectations

In everyday setups, the combination of re-filtration, CycleGuard, and a robust media stack helps maintain clear water and balanced ammonia/nitrite levels. The white housing offers a clean, unobtrusive look that blends with many tanks and décor styles.

Maintenance, tips, and warranty
