TMC Reef Sump – Marine Aquarium Filtration Sump S–XXL

TMC Reef Sump – Advanced Marine Aquarium Filtration

Upgrade your marine aquarium with the TMC Reef Sump, a versatile filtration system designed to improve equipment organisation, simplify maintenance and provide flexible filtration options.

Available in five sizes from S to XXL, the range caters for marine aquariums from compact reef systems to larger displays of up to 825 litres.

Efficient Mechanical Filtration

An integrated mechanical filter bag captures suspended debris as aquarium water enters the sump.

The specially designed inlet chamber helps diffuse bubbles and control incoming water movement, supporting efficient filtration and reducing unwanted microbubbles.

Flexible Refugium & Skimmer Chambers

The TMC Reef Sump includes a removable refugium baffle, allowing the filtration layout to be adapted to your aquarium's requirements.

Adjustable water depth helps accommodate compatible protein skimmers, while accessible chambers make routine cleaning and equipment maintenance easier.

Integrated Freshwater Reservoir

A dedicated freshwater reservoir with lid provides convenient storage for RO water used by an optional automatic top-up system.

This helps keep top-up water separate from the main filtration chambers and reduces the need for an external reservoir.

Built-In Equipment Management

Each sump includes practical features for organising your marine aquarium equipment:

• Four integrated dosing tube holders

• Triple monitoring probe holder

• Mechanical filter bag system

• Bubble-diffusing inlet chamber

• Adjustable water depth

• Removable refugium baffle

• Freshwater top-up reservoir
