UNS Pre Filter Pad - R90

The Pre Filter Pad is a mechanical pre-filtration media designed exclusively for UNS Reef Systems. Its multi-layer honeycomb structure captures large particles and debris, helping extend the life of filter socks and improving overall filtration efficiency. Easy to install, remove, and rinse, this pad simplifies routine maintenance while supporting clearer, more stable water conditions.

This size fits the R90 reef system sump and is compatible with the original Reef System series and Peninsula models. Includes 2 pads per order. Rinse regularly to keep flow strong.
