Item code: 5705
Model 50 offers both forward and reverse water flow. The use of reverse flow throuh an undergravel system promotes bacterial growth from the bottom up, increasing biological filtration capacity. The injection of water containing oxygen beneath the gravel bed helps to support superior conditions for beneficial nitrifying bacteria. Substrate maintenance is facilitated by debris being located near the surface for easy removal.
