Shark PRO 700 Internal Filter (185 GPH) - Sicce

The Shark PRO 700 is Sicce's redesigned take on the internal filter — built around a modular cartridge platform that solves one of the most common complaints about submersible filters: the hassle of maintenance. Rather than pulling the entire unit out of the water and interrupting flow, the magnetic quick-uncoupling system lets you detach individual filter cartridges directly while the pump continues running. That means less disruption to your tank's biological stability and a faster, cleaner service routine.

The modular design extends beyond convenience. The filter ships with two cartridge modules and filter foam ready to go, but the system accepts up to two additional cartridges, giving you room to add more mechanical or biological media as your bioload grows. Whether you're running a lightly stocked 32-gallon or a moderately stocked 53-gallon system, the Shark PRO 700 can be configured to match your filtration demands without swapping out the entire unit.

Flow is adjustable via a dedicated knob, so you can dial back output for sensitive livestock or fine-tune surface agitation in smaller setups. The integrated aeration system and spray bar provide surface oxygenation without the need for a separate air pump, and the unit is noted as turtle-friendly — making it a reasonable choice for paludariums or reptile enclosures as well as standard freshwater aquariums. Mounting is flexible: the filter attaches to glass up to 12mm thick via a strong magnetic mount and can be oriented vertically or horizontally depending on water depth and placement preference.

Assembly is tool-free, and the entire unit is made in Italy with a five-year guarantee from Sicce. At 7 watts, operating costs are minimal. For hobbyists who want reliable internal filtration with a maintenance workflow that doesn't require tearing down the tank, the Shark PRO 700 is a well-considered option.
