Trigger has been testing our PLATINUM series for over a year and a half to make sure we have a solid, proven design (but no one really cares as long as the design works). This series includes an automated, continuous mechanical filtration that replaces filter socks. They 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. The fleece rolls are 8″ or 10″ wide depending on the model and 150 feet long. Each sump comes with 2 rolls in the box.
This design will automatically roll new fleece to be filtered as soon as the fleece in the sump becomes dirty. Trigger 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. They have tested up to 3000 gph without any flow issues.
Trigger spared no expense on the PLATINUM line. They used a high torque motor which is critical when pulling the fleece in high flow applications and not burning up. They added a redundant shut off sensors 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.
Note that the time the fleece roll lasts and how much water flow can be pushed through may vary and depends on return pump flow rate and how dirty the water is (bio load). It is expected that the first roll will be used up faster as it polishes the water.
