CTC Aquariums offers customized glass filtration sumps including Berlin style, Refugiums and Wet/Dry bio-filters. Design a sump to fit your specific filtration and space requirements. Sumps include micron drain socks and mounting brackets, virtually any baffle-wall configuration, foam sponges and bulkheads as well as penetrations for external pumps, etc.

CTC also offers a wide array of overflow-box design in both internal and external configurations as well as completely unique and customized designs to provide the optimum filtration for your aquarium project. Aquarists are no longer restricted to a single corner overflow-box with one drain and one return line with no alternatives available. Internal designs include traditional corner boxes as well as trapezoid and island style overflow-boxes. We also offer external and internal “scupper-boxes” which have become immensely popular in recent years.
