Pisces – Live Media Biospheres Lg – 17 oz

Each media type is pre-colonized with live nitrifying bacteria and packaged in water to preserve bacterial health—so you can establish your biofiltration system safely and effectively from day one.

Unlike transferring rocks or filter media from older tanks—which can carry pests, algae, or disease—this is a clean, controlled solution that accelerates the cycling process without the risk.

Suitable for all freshwater and saltwater systems and compatible with any filter brand or style.
