Sicce's Shark Pro 700 Internal Filter is rated for tanks up to 53 gallons. It is a fantastic internal filter that includes a magnetic mount, flow regulation and 3 types of flow options. These are uni-directional flow, an integrated spray bar or an airline that allows for oxygenation from the uni-directional flow outlet.
You can add multiple modules to the filter through their 'magnet connecting system' that allows for more filtration in larger tanks.
Comes with a 5 year warranty (3 years + 2 years when you register it online!)
