TRUVU DLS Replacement 6 Inch Single Roll
Replacement DLS bio media roll for TRUVU AIO Aquariums
Fits the following AQUASYSTEMS: 50 R, 55 L, 55 FBH, 50 Bow
The 4” diameter X 6" tall rolls of DLS found in the Aquasystem and Mighty Max hang on wet dry 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.
