The Sea Side Aquatics CS3.5 is a compact and efficient cone-style protein skimmer designed to aggressively remove dissolved organic compounds from your saltwater aquarium. Utilizing a needlewheel impeller, it creates a dense cloud of fine microbubbles that bind to and extract waste proteins, fish waste, and uneaten food before they can break down into harmful nitrates and phosphates. This process is crucial for maintaining pristine water quality, promoting coral health, and ensuring a stable environment for all your marine inhabitants.

At the heart of the CS3.5 is a reliable and quiet Sicce SK200 pump, which draws an impressive 200 liters per hour of air for maximum waste removal. Its cone-shaped body enhances foam concentration and stability, leading to a more effective collection of skimmate. With a compact footprint of just 4.5 by 6.6 inches and a height of 17.1 inches, this skimmer is engineered to fit into tight sump spaces. It operates optimally in a water level between 8 and 10 inches, making it versatile for various sump configurations.

This skimmer is an excellent choice for reef hobbyists with aquariums ranging from 25 to 80 gallons. Its space-saving design makes it particularly well-suited for all-in-one tanks or systems with smaller, more compact sumps where equipment space is at a premium. If you are looking for a powerful, yet affordable, skimmer that delivers consistent performance and is easy to tune, the Sea Side Aquatics CS3.5 provides the perfect balance of efficiency, reliability, and value for small to medium-sized reef ecosystems.
