Overview The FUMAK U-V Aquarium Filter is designed to bring balanced filtration, oxygenation, and water movement to mid-sized tanks

Optimized for 10–40 gallon setups, this compact unit blends powerful performance with energy efficiency to support both fish and planted aquariums

Expect steadier water circulation, clearer water appearance, and adaptable operation that fits your tank’s needs without dominating the layout

In -world use, hobbyists often notice calmer surfaces, improved water turnover, and a more even distribution of filtration downstream

The U-V system is built to work with your tank’s inhabitants and décor, rather than overpower them, while remaining easy to install and adjust

Performance and efficiency Core specs meet everyday aquarium demands: a maximum flow of 130 GPH, a lift height up to 2 feet, and a modest 5 W power draw

The unit is designed specifically for tanks in the 10–40 gallon range, delivering filtration plus enhanced oxygenation and circulation to support a healthy environment for fish and plants

Designed for 10–40 gallon tanks, integrating filtration with improved oxygenation and circulation

Adjustable flow rate helps tailor performance to your bio-load and plant needs

Safety and build quality The filter is fully submersible, with an epoxy-sealed motor for added safety during underwater operation

Each unit undergoes water submersion and rigorous testing to ensure reliable, safe performance in a tank setting

Completely submersible and epoxy-sealed for underwater use

Rigorous testing to meet safety standards in aquatic environments

U-V lamp with timer The integrated 3 W U-V lamp supports green-water management, helping maintain a clean, clear water appearance

A built-in timer lets you program cycles at 4, 8, 12, or 24 hours, enabling periodic operation that can align with daily maintenance routines

3 W U-V lamp for green-water control and water clarity benefits

Timer options: 4/8/12/24 hours for flexible scheduling

parts: sponge (B0C2Y7FCCY) and lamp (B0C2Y961RL)

Filtration: three stages The three-stage filtration system tackles debris, odors, and biological balance: Stage 1 – Mechanical: coarse sponge pre-filter captures large residues

Stage 2 – Chemical: carbonized sponge removes odors, chlorine, and fine particles

Stage 3 – Mechanical & Biological: fine sponge polishes water and fosters beneficial bacteria

Modes of use: two versatile options Two operating modes address different tank dynamics and preferences: AERATING MODE — Includes an air venturi and tubing to boost oxygen delivery with adjustable airflow, supporting well-oxygenated water for fish

RAINFALL MODE — Directs filtered water to a spray bar, creating surface agitation and even distribution as water returns to the tank

Practical tips for setup and ongoing care For results, select media that suits your tank’s inhabitants, monitor flow adjustments as your bio-load changes, and replace worn components using the referenced search codes

Regular checks help maintain clarity and circulation without disrupting the tank’s balance
