The ASM G-1X is a powerful in-sump protein skimmer designed to efficiently remove dissolved organic compounds from your saltwater aquarium, leading to superior water clarity and a healthier reef environment. It operates by vigorously mixing air and water to create a dense foam that captures and exports waste before it can break down into harmful nitrates and phosphates. Constructed from durable extruded PVC tubing and injection-molded plastic, this skimmer is built for long-lasting performance inside your sump.

This skimmer features a highly effective needle wheel design on its included Sedra 3500 pump, a combination that generates exceptionally fine bubbles for maximum skimming action. Rated for aquariums up to 150 gallons, it maintains a compact footprint of just 8.5" x 11" and stands 22.5" tall, making it suitable for a wide range of sump configurations. The design emphasizes user-friendliness; simply place the unit in your sump, plug it in, and make minor adjustments to the outlet tube to dial in the perfect performance for your system.

Ideal for both new and experienced saltwater hobbyists, the ASM G-1X is a perfect choice for anyone seeking a reliable, set-and-forget protein skimmer for a medium to large-sized reef tank. Its straightforward setup and potent performance provide an effective and hassle-free solution for maintaining pristine water quality, which is crucial for the health of sensitive corals and fish. If you need a powerful skimmer that is easy to install and adjust, this model offers exceptional value and efficiency.
