The JBJ SK-45 is a high-performance protein skimmer designed to maintain pristine water quality in saltwater aquariums. Constructed from durable, high-quality cell cast acrylic, this skimmer effectively removes dissolved organic compounds and harmful toxins from your water column. It utilizes an advanced needle wheel impeller pump that generates a dense cloud of microbubbles, efficiently extracting waste and phosphates that contribute to nuisance algae, resulting in a cleaner and healthier aquatic environment.

Engineered for performance and convenience, the SK-45 features a compact footprint of just 3.75 by 3 inches, making it suitable for tight sump spaces. It includes an enhanced needle wheel pump, an adjustable flow rate control, and a Venturi adjustment valve for precise tuning. The large reaction column allows for maximum contact time and helps microbubbles evaporate before water returns to the tank, while a double media sponge traps any remaining bubbles. A large volume collection cup simplifies maintenance, and the included rimless mounting bracket with a water guard ensures a secure and clean installation.

This protein skimmer is an excellent choice for aquarists with tanks up to 45 gallons, and it is specifically designed to be a perfect fit for the JBJ RL-20, RL-30, and RL-45 all-in-one aquariums. Its simple setup, quiet operation, and powerful skimming capabilities make it ideal for both beginners and experienced hobbyists seeking an efficient, reliable, and compact solution for superior water filtration that leaves the display tank microbubble-free.
