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.
