200 Micron filter bag
Application: Refugiums & Sumps
The micron filter bag measuring 4” in diameter by 14” in length acts as a water polisher, trapping minute particulate matter as small as .007874 “entering refugiums and sumps!
The micron bag acts as a water polisher to finish the cleanup job initiated by the aquarium pre-filter.
DLS Pre-filter
Application: Internal and External Overflow
The DLS pre-filter is a mechanical filter, not a biological filter. The 5” diameter roll of DLS (Double Layer Spiral) material is interleaved with a polymeric material that effectively traps detritus to ensure a clean flow of water as it enters the wet/dry filter or refugium or sump.
