Fritz FuzzOut rapidly eliminates toxins, metals, and odours while restoring balance to essential trace elements in both fresh and saltwater systems. This pre-filled mesh bag works immediately—simply place one bag per 75 gallons in a high-flow area of your filter. FuzzOut tackles phosphates, reduces algae and organic buildup, and oxygenates your water column without mess or regeneration needed. For optimal results, remove after two weeks, perform a 20% water change, and retreat if hair algae persists. Suitable for aquariums of any size.
