Deltec FR Fluidised Reactor – Phosphate & Carbon Media Filter

Deltec FR Fluidised Reactor – Professional Aquarium Media Filtration

Maximise the performance of your aquarium filtration media with the Deltec FR Fluidised Reactor. Designed for marine and freshwater aquariums, this high-quality reactor provides controlled water circulation through specialist filtration media, helping maintain clearer water and improved nutrient management.

Particularly popular for use with ROWAphos phosphate remover, the Deltec FR range is also suitable for activated carbon and compatible biological filtration media.

Efficient Phosphate and Carbon Filtration

Unlike passive media bags, which may allow water to bypass the filtration material, the Deltec reactor directs water through the media chamber for consistent contact.

• Phosphate Removers: Ideal for ROWAphos and compatible media, helping control excess phosphate and reduce conditions that encourage nuisance algae.

• Activated Carbon: Helps remove discolouration and dissolved organic substances, improving water clarity.

• Biological Media: Suitable fluidised biological media can provide additional surface area for beneficial bacteria.

Advanced Fluidised Reactor Design

Water enters through a central downpipe before passing upwards through a diffuser plate, distributing circulation across the filtration media.

This encourages even water movement and helps prevent areas of poor circulation. Internal sponges retain finer media particles, while the adjustable outlet tap allows flow to be matched to the filtration material.

For phosphate removers, gentle movement is generally preferable to excessive tumbling, which can cause unnecessary media abrasion.

Easy Maintenance and Flexible Installation

The Deltec FR features a convenient twist-off bayonet lid, providing straightforward access when replacing filtration media.

Hose connections with removable unions simplify maintenance and allow the reactor to be disconnected without disturbing surrounding equipment.

The reactor can be installed within a suitable sump or externally, making it adaptable to different aquarium filtration layouts.

Regular media replacement and occasional cleaning of the internal sponges help maintain reliable circulation and filtration performance.

A Range of Sizes for Different Aquariums

Available in several models, the Deltec FR range accommodates different media quantities and filtration requirements.

Smaller models provide practical phosphate and carbon filtration for everyday reef aquariums, while larger reactors offer increased capacity for demanding systems.

Individual model specifications are available in the Technical Information tab.
