It has an 11W UV globe so it is very effective in dealing with unwanted algae. The filter is very efficient because it is uses a multi-stage filtration system: Stage 1 - Mechanical Filtration: The water is pumped into the filter (pump needs to be bought separately) to create pressure necessary to start the mechanical filtration stage. There are three foam discs which collects various sizes of organic debris which leads the growth of large numbers of beneficial microbes and bacteria which break down harmful pollutants in the water. Stage 2 - Biological Filtration: In this stage, the water passes through the bio-balls at the bottom of the filter. These bio-balls are where the beneficial microbes and bacteria grow in order to process harmful toxins of ammonia and nitrites into useful nitrates to support a healthy pond environment. Stage 3 - UV Clarification: This stage is where the water is clarified by eliminating microscopic suspended algae in the water. When it passes through the UV lamp, these algae are killed and this makes your water crystal clear. The filter can also be used to create decorative fountain to give your garden a great look and impress your guests and neighbours. In addition to the attractive look, it also helps oxygenate the water and this leads to healthy fish and plants. The outer shell is made of high-quality ABS which is strong and durable.
