  Home > 05a. Green Water - Ponds with filter systems - Crystal rapidly removes green algae >

 
 
 
 
 
A lovely pond can be a source of inspiration and pride. Whether you’re a commercial grounds keeper or a home pond owner you know algae can cause your pond to look green and ugly.
Typically, algae growth, odor emissions and sludge buildup, in lakes, ponds, waste water, etc., result from biological imbalance and flocculation (small single cell algae spread out across the surface of your pond.)
There’s some serious chemistry and research in the products we’ve spent nearly two decades developing; but in a nutshell…
These amazing eco-friendly crystals clear your ponds water by causing the single celled algae dirtying up the surface of your pond to clump together. Once clumped together they can be removed by your filters or fall to the bottom and decompose.
     
 
 
Mineral base powder 100%
biodegradable.
100g treats  1,250 litres and 1kg treats 12,500 litres(2,750 gallons).
Removes green and cloudy water - very rapidly - results can be seen in minutes. Controls and prevents green water and cloudy water for extended periods.
Each very small powder particle has millions of nano size holes, which by ion exchange help absorb nitrites, phosphates and other pollutants in the water. 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.
Activated by water it immediately starts to electrically charge individual algae cells so that they clump together, they now sink to the bottom of the pond were either the filter system will clear them or if there is no filtration, then they will decompose over time. Simply dose Hydra Crystal at pump outlet, broadcast over pond surface, or dilute with water and add as a slurry.
UV lights can be left on during treatment.
Maintains clear healthy clean water.
"pH Neutral" has no effect on waters pH. Dilution Rate 1:12,500
