Purpose and user

The JAHEA ZY-MINI is a 3 watt UV-C aquarium lamp designed for hobbyists who need to clear green water in tanks, ponds or pools. It targets algae and microorganisms with a 254 nanometre wavelength and includes a test card plus a temperature strip for verification.

Upgrade context

The light replaces manual scrubbing or chemical treatments by delivering UV disinfection that can kill up to 99.99 percent of bacteria in about 30 minutes. The jump is worth it when green water persists despite filtration and the keeper wants a reusable, plug-in device rather than recurring additives.

Build fit

The mini lamp connects with various filters and sits submersed while the power plug and controller stay dry. It frees up maintenance time with a suggested cycle of three to four hours every two to four days. The silica glass sleeve requires careful handling to avoid breakage and short circuits.

Questions about this item

How much space does the 3 W mini UV lamp need inside the tank?

The compact 3 W mini unit is designed to sit inside the aquarium or pond; keep the power plug and controller completely dry and away from any water source.

What is the correct way to start the UV disinfection cycle?

Press the button on the updated controller to turn the lamp on; run it for 30 minutes, then repeat for 3 to 4 hours every 2 to 4 days.

When should the silica-glass UV bulb be replaced?

The UV-C output drops over time; plan to change the bulb once the water no longer clears within the usual 30-minute cycle.
