TRUVU DLS Replacement 10 Inch Single Roll
Replacement DLS bio media roll for TRUVU AIO Aquariums
Fits the following AQUASYSTEM AIO Aquariums: 125 H, 135 T, 180 L, 240 L, 240 H, 300 T.
The 4” diameter X 10" 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.
