OASE CrystalSkim 350 - Grey Aquarium Surface Skimmer

The OASE CrystalSkim 350 is a compact, high-performance surface skimmer designed to keep aquarium water crystal clear by removing biofilm, floating plant matter, and dust from the water surface. Its innovative design improves oxygen exchange and supports a healthy aquatic environment. Unlike basic surface skimmers, CrystalSkim includes a bottom outlet that helps circulate water in dead spots where debris settles. Suitable for both freshwater and saltwater tanks up to 92 gallons (350 L), CrystalSkim features a floating intake ring that adjusts to changes in water level, ensuring consistent skimming even if the unit isn’t level. The individually adjustable flow rate lets you fine-tune the skimming action, making it ideal for planted tanks, shrimp tanks, and nano setups. The removable collection basket features fine intake slots that protect small fish and shrimp while capturing the smallest particles. Installation is quick and tool-free with strong suction cups. Engineered in Germany and made in Italy, the CrystalSkim is UL-certified, energy-efficient, and backed by a 3-year warranty; delivering reliable performance and premium quality you can trust.

• Quickly Clears Surface Debris – Removes biofilm, floating plant matter, and dust from the water surface to improve oxygen exchange and maintain crystal-clear water 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 with Floating Intake Ring – Fine-tune the skimming intensity with an adjustable flow dial. The floating ring adapts to water level changes to ensure consistent surface cleaning even in uneven setups. 
• Safe for Shrimp and Small Fish – Includes a removable collection basket with fine intake slots that protects delicate livestock, like shrimp and nano fish, while capturing the smallest particles that nets can’t remove. 
• Quiet and Compact Design – The low-noise motor and slim form factor make it ideal for aquascapes and display tanks where appearance and quiet operation matter. 
• Easy Setup and Maintenance – Attaches securely with suction cups and lifts out easily for cleaning. The removable basket makes routine maintenance simple and mess-free, while secure suction cups make mounting fast and installation tool-free. 
• Reliable Quality & Back 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.
