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.
