## Overview

The AA Aquarium Mini Green Killing Machine (AAUV3W) is a patented, UL-certified internal UV sterilizer designed for aquariums up to 20 gallons.

## Description

The Mini Green Killing Machine is an internal UV sterilizer for small aquariums up to 20 gallons. This submersible sterilizer keeps water clean and clear by killing algae that causes green water, pathogens and other harmful bacteria. Quick and easily to install in just 5 minutes. Includes 3 watt UV sterilizer bulb sealed in a durable plastic enclosure, water pump with filtration sponge, control box with LED indicator for bulb replacement, flow regulator, suction cup mounting and individual plugs for the pump and bulb.For optimal results, replace the UV bulb every 3 - 6 months.

Review: Algae beater - It did a great job on clearing my algae, took a while but the results were good. Delivery on time.
Review: Poor Value, Limited Working Life - For the first 4 months or so this steriliser worked perfectly. Then I started to notice a slight increase in algae on the glass and plants. By the end of the 5th month the aquarium looked like a bomb site. The lamp unit is sealed so you can't clean it or replace a dying bulb. I paid around £25 for this unit which is now becoming increasingly difficult to find in the UK. A replacement lamp unit is currently around £18. In short, it's a poor buy. Look elsewhere.
