Hailea RP-400 Internal Filter

Using a three stage filtration system, the Hailea filters are sure to leave your tank crystal clean.
Firstly the filter runs the water through a course sponge to catch debris. Then the water is passed through a pores sponge which houses good bacteria and then finally the water passes through the carbon section of the filter which removes contaminants and impurities such as algae using chemical absorption. 
The RP-400 filter, filters 400lph and is suitable for a 200L aquarium.
