Blue Torrent Black Diamond Cartridge Filter 525 Sq. Ft.
Get longer runs between cleanings and crystal-clear water. The Black Diamond 525 packs an extra-large 525 sq. ft. of fine-mesh cartridge area to trap more dirt, sunscreen, and fine silt—so you backwash never and rinse far less often. Its low-restriction design pairs perfectly with variable-speed pumps, delivering strong turnover at lower RPMs for quieter, cheaper filtration. A robust tank with a quick-access clamp, easy-read pressure gauge, manual air relief, and bottom drain makes service fast: pop the lid, hose the elements, and you’re back online in minutes.
Built for season-after-season clarity, the Black Diamond 525 uses corrosion-resistant materials and large-format plumbing to keep flow high and pressure low. It’s a smart upgrade for busy families and light-commercial pads that want fewer shutdowns, cleaner water, and simpler maintenance—no messy sand changes, no D.E. handling.
