MAX C-Series Rear Sump

  The MAX C-Series aquariums are divided into 2 parts, Aquarium and the Rear Sump that discretely houses all of the filtration and circulation systems. The MAX C-Series sumps contain multistage filtration consisting of a REEF-SPEC® protein skimmer, activated carbon and mechanical filter materials. The sump has dedicated space available for additional chemical filter media as well as the addition of a chiller.

Detachable Surface Skimmer

The water flows from the aquarium to the rear sump via a detachable surface skimmer (1) located across the top of the dividing glass wall that directs the organics laden water from the upper surface of the tank into the sump. Each section of the surface skimmer is detachable for easy maintenance.

Protein Skimmer

The heart of the filtration system is the protein skimmer (2). The all new MSK 600/900 skimmers developed for the MAX C-Series implement Red Sea’s® criteria for SPS corals, passing the entire volume of the aquarium water through the skimmer at least 3 times per hour and with a 3 to 1 water to air ratio. The new design of skimmers is not affected by the regular fluctuation in the water level of the rear sump due to evaporation, and has an adjustable outlet gate to maintain the optimal skimmate consistency which will vary according to actual water conditions. The new skimmer pump and impellor run cooler and quieter than before and the built in silencer on the air intake does a great job of eliminating skimmer noise.

Skim Adjuster

Red Sea’s MAX C-Series All new MSK 600/900 protein skimmers are easily adjusted by raising and lowering the Skim Adjuster that sets the water height within the neck of the skimmer. Additional control is available when required by adding the optional valve on the air intake.

Media Rack

A dedicated media rack (3) provides a convenient system for maintaining the various filter media such as the phosphate-free high quality carbon (4) that is supplied with the system.

Chiller Ready (Optional Chiller Kit)

The Red Sea MAX C-Series sump has a dedicated place for the addition of a chiller pump (11) as well as a convenient connection bracket (10) for the chiller piping (Chiller and pipes are not supplied with the system).

REEF-SPEC® T5 Lighting (In MAX C-250 only)

The Red Sea MAX C-250 aquarium is supplied with Red Sea’s REEF-SPEC®  T5 tubes to provide the ideal PAR and intensity for SPS corals. Each C-250 has the following combination of tubes: REEF-SPEC® BlueWhite 3 x 39W REEF-SPEC® Actinic 2 x 39W REEF-SPEC® Pink 1 x 39W

In Cabinet Power Center

The power center for the MAX C-Series has been relocated to a convenient position within the cabinet. The 7 channel power centre operates all of the stock items as well as providing at least 2 spare switched outlets for optional equipment such as a chiller. Safety features include a splash cover over the power outlets as well as a built in circuit breaker for overload or short circuit protection.

Plastic Corner Protector

Internal plastic corner inserts that form a standard part of the aquarium construction will ensure that the clean lines of the front corners will be maintained forever.
