Trigger Systems Platinum 39 Sump - 39 Inch

Trigger Systems has been testing their 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 automatically rolls new filter fleece as the older fleece becomes dirty, replacing the need for 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. Triggers fleece rolls can last from 4 to 6+ months, unlike filter socks that need to be changed every few days. Their beta testers have 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.
