The EHEIM Pro 4+ 600 Aquarium Canister Filter is a great way to keep your finned friend’s water column crisp and clean! It features virtually silent operation with powerful performance that’s optimized for energy efficiency, delivering an adjustable flow rate of up to 330-gallons per hour using only 16-watts. Equipped with a self-priming aid, top prefilter and locking safety hose adapters, it is engineered to be an easy and convenient way to keep your underwater companions comfy. The “Xtender” button is also a helpful addition that uses a bypass to skip over the fine filter pad—should it become blocked—to reduce the need for additional cleanings. Suitable for both freshwater and saltwater water aquariums, this sleek, black unit employs four individual filter baskets to keep tanks ranging from 65-gallons to 160-gallons looking their best. This is also great for use with Aquatic Turtles, Aquatic Amphibians, and Invertebrates.
