The Obsidian fleece roll sumps have a lot of the same features found on our Platinum fleece roll sumps but instead of having an automated controller, the Obsidian sumps have a turn dial to advance the fleece roll. Simply turn the dial to remove the dirty fleece and roll in new clean fleece. This provides a more affordable option on a sump that has the fleece roll system built in and sized for the sump, which we found to be the most efficient design. Our fleece rolls have been lasting 4 to over 6 months, unlike filter socks that need to be changed every few days. You can also purchase the Obsidian Upgrade Kit at any time and upgrade to our new 2nd version of our automated controller that features optical sensors and a small screen to configure a bunch of options.

The Obsidian line is offered in two sizes: 34″ and 39″ where both use the fleece rolls that are 10″ wide.

This design will need to be manually rolled regularly, but if not there is an overflow outlet that prevents from any flooding. This design has the same diamond pattern found on the Platinum sumps for the water to flow through purposely using 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.
