The new GEO Automatic Filter Roll sumps (AFR) are feature rich with all the standards of the previous GEO R Series lines. GEO has partnered with Clarisea, the most advanced manufacturer in AFR to bring you the next generation of aquarium mechanical filtration integrated into the GEO sump. The GEO AFR sump comes in 4 sizes with the 46″ and 36″ using the Clarisea SK-5000 roll and the 30″ and 24″ using the Clarisea SK-3000 roll. Each roll is 50 microns and replacement rolls can be easily found throughout the web. The flow rates for the SK-5000 is 1200 gph and for the SK-3000 is 800 gph. One roll will last on AVERAGE 30 days but may vary due to the water conditions of the individuals aquarium.

GEO’s integration of the Clarisea AFR makes it the easiest roll to change with a clearance of only 21″, which is less than most protein skimmers on the market. The proprietary AFR slide on the top of the sump is easily removable for maintenance and new roll change outs. GEO makes it simple for you to feed the roll material with their proprietary removable pin rollers. There is no threading through the needle to get started. Just lay the material in the basket and slide the pin rollers over the material.
