Features and Benefits

  • Hydra Quartz string algae treatment are easy to use granules which work on contact
  • Hydra Quartz is your key to improved pond balance.
  • Same eco friendly bacteria action as barley straw but with rapid results
  • No waiting weeks for results with no messy, smelly straw to remove

  • Harmless to all fish, birds, reptiles, invertebrates, humans, mammals, animals and water plants ( Do not use in dry form around water plants. Dilute with water and pour around the plants to remove string algae from the plants)
