The Triton series is designed to work with the Triton method which is becoming increasingly popular as it does not require water changes, which no one enjoys. One of the main requirements for the Triton method is to have a refugium sized at roughly 10% of the display tank volume. The TRITON20C refugium will hold 9 gallons when at the highest water level setting (11.5″) allowing it to support tanks up to around 90-100 gallons. The V2 design incorporates a filter sock holder on the main inputs for mechanical filtration to polish the water from time to time if needed. Also, this feature allows you to move back to the more traditional filtration method with filter socks in the future.

The TRITON2OC has 3 main sections. Water enters the sump through the input fittings. A filter sock holder allows for placing 4″ filter socks under each input. Water then flows through the large refugium section that has a lid to prevent noise and water evaporation. Water then flows towards the front of the sump and then to right through the overflow teeth in the adjustable wall into Section 2.

Section 2 is typically where the protein skimmer is located. Water purposely exits Section 2 by flowing under the aquamarine wall to allow proteins to remain at the surface maximizing the potential for the protein skimmer to extract from the system. The water then flows through the media platform and foam filter block into Section 3. The media platform can be used to allow for several different filtration methods (bag of carbon, bio balls, bio media, rubble rock, etc.).

Section 3 is the return section where the return pump will sit, pumping water back to the display tank.
