The MAX REEF-SPEC® performance criteria is the result of Red Sea’s years of research into the sustainable growth of allcorals, including the most delicate “SPS” corals, in a artificial reef environment.

MAX C-250 Rear Sump

The Red Sea MAX C-250 aquariums are divided into 2 parts, Aquarium and the Rear Sump that discretely houses all of the filtration and circulation systems.
The MAX C-250 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.

MAX C 250 Protein Skimmer

The heart of the filtration system is the protein skimmer (2). The all new MSK 900 skimmers developed for the Red Sea MAX C-250 implement Red Sea’s REEF-SPEC® 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-250 all new MSK 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.
