Infinity Series AquaFlow HOB Aquarium Filter – Freshwater & Saltwater

Keep your aquarium water clean, clear, and properly circulated with the Infinity Series AquaFlow Hang-On-Back Filter. Its compact waterfall design provides dependable multi-stage filtration without complicated plumbing or equipment inside the aquarium.

Available in four sizes, the AquaFlow series works well for freshwater aquariums, shrimp tanks, betta setups, community tanks, nano systems, and lightly stocked saltwater aquariums.

Three-Stage Aquarium Filtration

The AquaFlow HOB Filter supports three essential types of filtration:

• Mechanical Filtration: The included filter sponge captures fish waste, uneaten food, dirt, and suspended debris.

• Biological Filtration: Biological media provides surface area for beneficial bacteria that help maintain stable water quality.

• Chemical Filtration: Additional space allows optional activated carbon or other chemical filter media to be added as needed.

Quiet Waterfall Circulation

The waterfall-style return helps circulate and oxygenate aquarium water while providing gentle surface movement. Its hang-on-back design preserves valuable space inside the aquarium and allows convenient access during routine maintenance.

Models and Recommended Aquarium Sizes

Aquarium-size recommendations are general guidelines. Stocking level, feeding habits, actual water volume, and desired turnover should also be considered when selecting a filter.
