  • Benefits of Hydro FilterSilk™ Filter Media

    Hydro FilterSilk™ is designed to be used in “bulk” and fill bio media chambers. In bulk it has more surface area than filter pads, but contains 90% open space. Open space within filter media allows for oxygenated water to easily pass through. Oxygen is the lifeblood of the beneficial bacteria inside a biological filter.

    Being much less dense than filter pads, Hydro FilterSilk™ can be rinsed with low pressure water. Rinsing filter media with low pressure water preserves the beneficial bacteria living on the filter media.
