TARARIUM Small Fish Tank Filter | 10-20 Gallon, 120GPH UV Submersible

Crystal-clear water for 10-20 gallon aquariums

In many home setups, cloudy or green water can obscure what you love most about your aquatic life. The TARARIUM Small Fish Tank Filter is engineered for 10-20 gallon tanks and aims to help bring clarity over time. In practice, water quality often improves within 4-10 days, with larger tanks requiring a little more time. The result is a clearer view of your fish, turtles, and plants, and a reduction in the frequency of water changes.

Two-stage filtration for dependable clarity

The filter integrates a first-stage Biochemical sponge with a second-stage UV light at 254nm. This dual path targets particulates, odors, and microalgae, helping you maintain a healthier-looking aquarium and easier maintenance.

Independent controls for flexible use

Separate switches let you run the water pump and the aquarium light on their own. When you want filtration only, you can disable the UV light without removing the unit.

Odor reduction and a fresher scent

Green water and standing water can carry noticeable smells. The TARARIUM unit is designed to help curb unpleasant tank odors, contributing to a more inviting home aquarium environment.

Compact versatile and aquarium friendly

With its compact footprint, this filter fits a variety of setups, including betta tanks, goldfish bowls, guppy tanks, small turtle enclosures, and select reef systems. It supports clearer water while potentially reducing the need for frequent water changes.

Optimized placement and daily use tips

Install near a rear corner with intake facing outward to minimize debris settling. Keep it free from substrate, and check the UV lamp and sponge during routine care to maintain flow and performance.

What you might notice day to day

Expect clearer water and brighter fish colors as the tank stabilizes. The device blends into most setups, and the independent light control allows nighttime viewing or daily lighting to suit your routine.

Maintenance for longevity

Regular rinsing of the sponge and a quick UV lamp check help sustain flow and clarity. A simple schedule supports stable conditions for your aquatic life.
