Devopet Aquarium U-V Light — Algae Control, 1-24H Timer, 3W for 3-20 Gallon Tanks

Compact UV-C solution for small tanks

The Devopet Aquarium U-V Light is a compact 3W UV-C device designed for 3-20 gallon freshwater and saltwater aquariums. Its slim, unobtrusive profile slips into tight spaces, keeping betta tanks, nano setups, and turtle habitats looking clearer and more inviting.

With thoughtful design and easy operation, this light targets green tint and helps improve water visibility without dominating the tank’s look. The 254nm wavelength is tuned for effective single-point algae control, while the unit’s small footprint makes it simple to position near key water flow paths. Note that a pump is not included, and optimal performance comes from steady flow, such as placing the lamp near the filter outlet.
