INNOVATIVE SKIMMING: This aquarium skimmer quickly and effectively removes floating debris, plant remains, duckweed, and the persistent surface biofilm that can hinder gas exchange, ensuring a crystal-clear water surface. IMPROVED GAS EXCHANGE: By breaking down thick surface biofilms, the CrystalSkim 600 significantly improves gas exchange, supporting healthier oxygen levels for fish and stabilising CO2 levels for plant growth. PERFECT FOR PLANT TRIMMING: After trimming aquarium plants, the skimmer captures even the finest plant fragments that are difficult to remove with a net, making post-maintenance cleanup faster and easier. INDIVIDUALLY ADJUSTABLE MOTOR: The powerful, adjustable motor ensures a clean water surface at just the right output, allowing you to tailor skimming performance to the needs of your aquarium. SAFE DESIGN: The slim, compact profile has an integrated safety basket to prevent fish or shrimp from entering the mechanism, ideal for tanks with small or delicate species.
