Nishikoi Clear Waters GH Booster provides essential general water hardness to create stable pond conditions ideal for fish and other aquatic life.

The joint hardness of the water is determined by the amount of calcium and magnesium and is referred to as general hardness or GH, which should not be confused with KH which is the measurement of carbonate hardness. The ideal GH level in a pond is a value between 10-15DH and it is important to the overall condition of the pond that these parameters are maintained and monitored through regular water testing.

Fish, pond plants and micro organisms grow optimally in the correct GH conditions. The supply of oxygen to aquatic life is best safeguarded at the correct levels too, but owing to weather conditions such as rain and snow and the natural process of the pond and biological filters the GH will continuously be softened, and if the GH reaches a level of 10DH or below the hardness should be increased using Clear Waters GH Booster.

Regular testing of the GH in the pond is recommended and is particularly important after rainfall and in situations where GH is expected to have been consumed or diluted at a high rate.

Dosage:
Gradually increase the GH by adding Nishikoi Clear Waters GH Booster over a 24-48 hour period and re-test between doses until the desired levels are reached.

Each 25ml of GH Booster will raise there general hardness by 2.5 degrees per 250 litres (60 gallons) of water.

Mix the correct amount in a bucket or watering can with warm (not hot) water and distribute evenly over the pond surface avoiding direct contact with desirable water plants.
