PondCare® Ammo-Rocks® 10 lb Bag

PondCare® Ammo-Rocks®

Ammo-Rocks can be used as a biological filter media with any type of pond filter. Use at least one 10 lb bag for every 300 gallons of pond water for best results.

Ammo-Rocks is a biological filter media and will not filter out fine particles and is not intended to replace particulate filtration materials, such as foam and brushes.

Place Ammo-Rocks in your filter in the same location as your current biological filtration media. Leave as much of your current media as space allows.

For best results Ammo-Rocks should be replaced annually at the start of the pond season.
