TRUVU 4" DLS SINGLE ROLL
The 4” diameter X 4" tall rolls of DLS found in the Aquasystem and Mighty Max filters are highly effective biological filters. The DLS (Double Layer Spiral) material interleaved with a polymeric material effectively separates the layers allowing the water from the aquarium to rain down through the DLS rolls where beneficial aerobic bacteria oxidize ammonia and nitrites.
