Zeolite Ammonia Remover is a natural
ammonia-removing mineral for use in freshwater aquariums. It works well in both
newly set-up aquariums to help prevent "new tank syndrome" and in established
aquariums to prevent sudden "surges" in ammonia. Comes in a 6 1/2" x 6 1/2"
fully rechargable pouch.
One pouch treats 55 gallons. Pouches should be replaced every 1-3 months. Place
pouch above filter foam pads.
