Trigger Systems has been testing its Platinum series for over a year and a half to make sure they have a solid, proven design. This series includes an automated, continuous mechanical filtration that replaces filter socks. Trigger has tested several different designs and found that having the fleece roll system sized to the sump is by far the most efficient. Their fleece rolls have been lasting 4 to over 6 months, unlike filter socks that need to be changed every few days. Every user so far has reported improved water quality, with some stating algae is no longer a problem. Trigger Systems Cube 20 Sump uses a 8" wide x 150-foot long fleece roll that is included. 

  • Magnetic Sensor Slider
  • Moveable and Removable Middle Partition wall
  • Input Plate Gasket Reduces Salt Creep
  • Four Dosing Tube Quick Connects
  • Polycarbonate Lid Over Fleece Chamber
  • Adjustable Water Level & Self Adjusting Top Platform
  • Laser Engraved Water Markings
  • Additional 1" Input Fitting for Modularity


This design will automatically roll new fleece to be filtered as soon as the fleece in the sump becomes dirty. Trigger Systems created a diamond pattern for the water to flow through which follows the gem theme, but purposely uses the most surface area on the fleece. Maximizing surface area is key in this design to allow the fleece to last longer and to allow for more water flow.


There was no expense spared on the Platinum line. Using a high torque motor is critical to prevent overheating when pulling the fleece in high flow applications. They added a redundant shut off sensor to ensure the fleece roll stops when the return pump shuts off. There are wire channels that hide the wires. On all models except the cube, the middle wall that separates the skimmer and refugium sections is move-able and removable allowing you to ensure your skimmer fits and maximizing the area for the refugium. Or you can remove and have one large chamber. A few more details and specs are listed below.

2x Trigger Fleece Roll


Note: The time the fleece roll lasts and how much water flow can be pushed through may vary and depends on the return pump flow rate and how dirty the water is (bioload). It is expected that the first roll will be used up faster as it polishes the water.
