ProClear Redflex Reef Sump

ProClear RedFlex Reef Sump – Premium Saltwater Aquarium Filtration System

Upgrade your marine aquarium with the ProClear RedFlex Reef Sump, a premium filtration system designed to deliver efficient water management, versatile filtration options, and convenient equipment organization. Manufactured by ProClear Aquatic Systems, the RedFlex Reef Sump combines durable acrylic construction, innovative filtration features, and practical functionality to support healthy, thriving saltwater aquariums.

Available in five sizes, the RedFlex Reef Sump series accommodates a wide range of marine aquarium systems, from smaller reef displays to large custom saltwater installations. Its distinctive red and white acrylic construction provides a professional appearance while offering dedicated compartments for essential aquarium filtration equipment.

The RedFlex Reef Sump features a multi-stage filtration design that supports mechanical, biological, and supplemental chemical filtration. Integrated 4-inch filter socks help capture suspended debris and waste before it circulates through the remaining filtration chambers, promoting cleaner water and improved filtration efficiency.

Designed with convenience in mind, the sump includes adjustable water-level functionality, allowing aquarists to accommodate compatible protein skimmers and other filtration equipment. Bubble diffusers help reduce microbubbles returning to the aquarium, while integrated holders for probes, dosing lines, and cables help maintain an organized filtration system.

The spacious equipment compartments provide room for compatible protein skimmers, heaters, return pumps, and additional filtration accessories. By relocating equipment beneath the display aquarium, the RedFlex Reef Sump helps maintain a clean, unobstructed viewing area while providing easy access for routine maintenance.

Adding a properly sized sump also increases the total water volume of an aquarium system, helping improve overall water stability. This additional capacity can contribute to more consistent water parameters, which are particularly important for sensitive marine fish, corals, and invertebrates.
