• Custom Precision-Cut Fit: Tailored specifically to drop seamlessly into the UNS Delta 120 filter media caddy with zero water bypass around the edges.
• Durable & Washable Foam: High-resilience cell structure allows repeated rinses in tank water during routine maintenance without losing shape or density.
