Hydra International - Natural Aquatic Treatments, Cleaning & Protecting the Environment

Removes ammonia in water, for use in ponds and fountains containing fish & aquatic life.

• Highly effective, micro porous crystalline structure effectively absorbs ammonia.
• Works by absorbing toxic ammonia in water in exchange for harmless sodium ions.
• Ideal for ponds with heavy fish loads or filters which have just been cleaned.
• Allows biological filters to develop more rapidly at the beginning of the season.
• This has been the Japanese pond keepers secret for hundreds of years.

Before using in your pond, the Ammonia Lock requires charging in a 10% salt solution. Leave the product soaking for 24 hours.

The Ammonia Lock may become saturated before reducing your ammonia levels to zero. In this case, you will need to recharge the Crystals again. Be sure to test your water using an Ammonia test kit if you are unsure.

Usage Rates

• 1 kilo treats 1,350 litres of pond water.
• 5 kilos treats 6,750 litres of pond water.
• 20 kilos treats 27,000 litres of pond water.
• Simply recharge with common salt using a 10% solution

For fresh water systems only - Not to be used in salt water systems.

Removes ammonia in water, for use in ponds and fountains containing fish & aquatic life.

Too much ammonia in your fish pond can build up and be potentially hazardous to aquatic life. Ammonia normally comes from the metabolic waste excreted by fish in your pond therefore the overfeeding of fish in your pond or lack of adequate biological filtration can exacerbate the problem. In natural ponds and lakes, ammonia is not usually so much of a problem, as there is a good through flow of water, but in man-made garden ponds, the over feeding of fish and unnatural environment makes ammonia levels more of an issue.

Ammonium (NH4) is constantly changing between Ammonium and Ammonia (NH3) and Hydrogen ions in water. This equilibrium is affected by changes to the pH and temperature of your water.

The figures refer to the maximum long term level of Ammonia in mg/litre that can be tolerated for healthy fish. As pH rises and temperature climbs, less and less Ammonia can be tolerated.
