Expert Advice

Our friendly staff are here to help call us on 01406 425138 to discuss your needs


As hobbyists, with each new aquarium that we own we learn how to identify and improve small details in the design. We incorporate these ideas into our next “perfect system”.

The D-D Reef Pro Aquarium

With the D-D Reef-Pro Aquarium we have taken decades of continuous improvements and incorporated them into our own version of the “perfect system”.  It’s affordable and suitable for both beginners or advanced aquarists.

Highly flexible design

The flexible design provides an easy to use robust system that can be tailored to suit even the most demanding aquarist and includes all of the essential features required for keeping a successful aquarium.
