The Shark Skimmer 300 from Sicce is an internal protein skimmer built for marine biotopes where space, noise, and energy draw are all considerations. It combines counter-current skimming with a diffusion-enhanced system and an adjustable water entrance, giving you control over the volume and character of skimmate produced. The result is efficient organic waste removal without the footprint or power demands of larger external units.
The body is opaque by design, blocking light from reaching internal components and preventing the algae colonization that plagues clear-bodied skimmers over time. The unit is also ozone compatible, which is a meaningful option for hobbyists running ozone as part of a water quality regimen. Together these details reflect a considered approach to long-term usability rather than out-of-box performance alone.
Maintenance is straightforward. The self-cleaning impeller reduces how often you need to pull the unit apart, and when you do, the skimmer is designed for easy dismounting. A cleaning brush ships in the box. At 83 x 125 x 243 mm and 6 watts of consumption, the Shark Skimmer 300 is genuinely unobtrusive — appropriate for display tanks where aesthetics matter as much as function.
Bioload is the critical sizing variable here. Sicce rates this skimmer for up to 300 liters at low bioload, 200 liters at medium bioload, and 100 liters at high bioload. Choose your capacity honestly based on stocking level and feeding habits rather than total tank volume alone. The required immersion depth of 130–150 mm makes it compatible with a range of sumps and display tanks, but verify your water column depth before purchasing.
