Fluval SK400 Surface Skimmer Spares unlike other commercially available productsThe SK400 Surface Skimmer removes unwanted water surface film to help improve oxygenation and light penetration for a cleaner and healthier aquarium.

These films are not only visually unsightly, but also reduce dissolved oxygen (required by fish to breathe) and decrease light levels (needed by live plants to grow).
