Additional Information

The cabinet hides a sump that is a hybrid of glass and movable plexiglass partitions. which allow you to customise the layout to accommodate your protein skimmer, pump etc.

The twin height adjustable baffles enable the exact adjustment of the water height to suit the equipment used. A separate top up chamber towards the read of the sump also offers room to install an auto top up system.
