RLD Series Ultra Quiet HOB Waterfall Filter with Oil Skimmer

Aquarium Hang-On-Back (HOB) Waterfall Filter | RLD Series

The RLD Series Ultra Quiet HOB Waterfall Filter is engineered as a premium Aquarium Hang-On-Back (HOB) Waterfall Filter for modern aquariums. This all-in-one filter combines ultra-quiet performance, a built-in oil skimmer, and modular media design to deliver pristine water conditions. Unlike bulky internal filters or complex canister systems, this compact HOB Waterfall Filter fits securely on tank rims, offering customizable flow and easy maintenance for any freshwater or saltwater setup.

Why choose the Ultra-Quiet RLD Series HOB Waterfall Filter

The RLD Series Ultra Quiet HOB Waterfall Filter stands out as a top-tier Aquarium Hang-On-Back (HOB) Waterfall Filter by solving common aquarium filtration headaches. Here’s why this versatile filter is the right choice:

Ultra-Quiet Operation (<60dB) – The Ultimate Quiet Flow HOB Filter

Powered by a precision brushless motor with anti-vibration padding, this filter runs at a mere ≤60dB—quieter than a soft fan. This makes it the perfect Ultra Quiet Aquarium Filter for bedrooms and offices, eliminating the disruptive hum of standard Aquarium Wall-Mounted Filters.

Built-In Oil Skimmer – Clear Surface Aquarium Filter

The integrated Surface Skimmer (a key feature of this filter) instantly removes floating oil film and debris. This all-in-one design ensures your tank’s surface stays crystal clear, boosting gas exchange without needing extra equipment.

Modular Filter Media – Customizable HOB Filtration

Our Customizable Filter Media design lets you arrange sponge, ceramic rings, or activated carbon to suit your tank. Whether you’re maintaining a goldfish tank or a delicate planted aquarium, this modular filter adapts to your needs.

Adjustable Flow Control – Full Control Over Your Waterfall Filter

A precision valve allows flow adjustment from 50% to 100%. This filter caters to slow-flow species like bettas, or high-circulation setups for cichlids and lush planted tanks, giving you full command of water movement.

Simple Low-Maintenance

Maintenance takes only 10 minutes every 2-4 weeks. Rinse the sponge in old tank water (not tap water) to preserve bacteria, clean the oil skimmer cup, and replace media as needed.
