Additional Information

The ReefSys range is a beautiful, sleek marine fish tank. The most outstanding feature is the ultra clear, low iron glass that is immediately evident. 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.

The ReefSys runs a twin overflow pipework configuration that enables large volume flow. The important emergency overflow standpipe is incorporated within the weir. Balancing the water level is made easy through the highly precise gate valve, which ensures near silent operation.

The UK manufactured cabinet impresses with clean, minimalist lines, soft touch door mechanism and six different hand selected Egger finishes.
