The Cobalt Clearvue Internal Filter has a unique, innovative design that has the beginner fish keeper in mind, but the performance that a hobbyist will appreciate. The filtration chamber makes it very easy to see when the filter needs to be replaced or cleaned. The bottom mounted motor and omni-directional output make the filter very flexible in placement and use. It can even be used in terrarium environments to create water fall effects. With three models from which to choose, the Clearvue 20, 30 and 45 are easy to use and have low power consumption and robust flow rates for their size.
