Coralife 300G Cone Protein Skimmer for Marine & Reef Aquariums

Keep your saltwater aquarium crystal clear with the Coralife 300G Cone Protein Skimmer. Engineered for outstanding protein removal, this high-performance skimmer utilizes a patented needle-wheel impeller, aspirating venturi, and advanced cone-shaped reaction chamber to efficiently remove dissolved organic waste before it can impact water quality.

Designed for marine aquariums up to 300 gallons, the cone-shaped body naturally concentrates foam while reducing water between air bubbles, producing a drier, more concentrated skimmate. The result is improved nutrient export, enhanced water clarity, and a healthier environment for fish and corals.
