Pond before treatment with Hydra Crystal

Product Highlights

  • Clears green and cloudy water
  • Use in ponds and lakes containing fish and aquatic life, domestic and exotics, for a crystal clear pond
  • Cleans dirty, murky ponds

Features and Benefits

  • Activated by water, Hydra Crystal immediately starts to electrically charge individual algae cells so that they clump together; they sink to the bottom of the pond, where either the filter system will clear them or, if there is no filtration, they will decompose over time
  • Mineral base powder is 100% biodegradable
  • Very rapidly removes green and cloudy water—results can be seen in minutes
  • Each very small powder particle has millions of nano size holes, by which an ion exchange helps absorb nitrites, phosphates and other pollutants in the water
  • Maintains clear, healthy, clean water
  • Controls and prevents green water and cloudy water for extended periods
  • Does not affect biological filters or pumps
  • Safe on concrete and synthetic liners
  • Harmless to all fish, birds, reptiles, invertebrates, humans, mammals, animals and water plants
  • Residual chemicals, including salts may interfere with the Hydra Crystal’s clearing process. To determine if prior treatments will be a factor in your pond, please use the jar test with a sample of our product before treating your pond. Request Sample here.

Hydra Crystal Treatment
Ensure adequate aeration by water pump or air-stone. Allow plenty of time to observe fish. Clean mechanical filters before starting treatment and keep these filters clean during treatment. Either dose Hydra Crystal at pump outlet, broadcast over pond surface, or dilute with water and add as a slurry. Circulate treated water throughout for even mixing and distribution. Leave UV and pump switched on. In extreme cases if no improvement is seen, repeat application after 48 hours.
