QUICKLY CLEARS SURFACE DEBRIS – Removes biofilm, floating plant matter, and dust from the water’s surface to improve water clarity and support healthy oxygen exchange. Designed for use in both freshwater and marine aquariums.
IMPROVES WATER CIRCULATION – In addition to surface skimming, the built-in bottom outlet creates gentle flow in low-circulation zones where debris tends to collect. This helps reduce dead spots and supports overall tank health.
ADJUSTABLE FLOW & FLOATING RING – Customize skimming performance with an individually adjustable flow rate. The floating ring automatically adapts to changes in water level, maintaining consistent surface cleaning even when the unit isn’t perfectly level.
SAFE FOR SHRIMP & SMALL FISH – A removable collection basket with fine intake slots protects delicate livestock while capturing the smallest particles that nets can’t remove. Ideal for planted tanks and aquascapes with shrimp or nano fish.
RELIABLE QUALITY & BACKED BY WARRANTY – For aquariums up to 92 gallons (350 L). Italian-made, German-engineered, UL-certified, energy-efficient, and backed by a 3-year warranty.
