All Clear

Provided that it will be dosed correctly, All Clear is harmless for plants and fish, whereas the microfauna will hardly be attacked. Fibrous and / or slimy algae can develop explosively under certain circumstances in a pond. In that case the pond water will always be more or less clear, whereas it is conspicuous that the pH value is high (8.5 - 9.5) and carbonate hardness (CH value) low. Besides, the growth of oxygen producing plants leaves much to be desired and the number of plants in proportion to the water content of the pond usually is too small. To solve the problem of fibrous algae the following measures should be taken:

1. If not yet present, apply pond substrate. At least 80% of the bottom surface should be covered. Mix a dose of Bacterial with the pond substrate.
2. Take care that the total hardness of the water (JH value) is at least 8 °GH (increase, if necessary with the help of JH Plus or Mineral Plus).
3. Apply more pond plants. Suitable kinds in this phase are: floating plants and water lilies.

The measures stated here aim at reducing the growth of algae by biological means and finally to stop it. They strengthen the capability of bacteria to degrade and optimize the growth of water plants (hardness at least 8 °GH). Moreover, by applying more pond plants, the richness in food of the water will be reduced. Besides these measures it is wise to remove fibrous algae continuously by hand. If, after a certain lapse of time, algal growth is reducing noticeably, oxygen producing plans can be applied.

The whole process will take a number of months. This period can be shortened if, prior to taking the measures referred to, a course of treatment, using the algae killer All Clear, will be applied. It should be considered, however, that All Clear fights the algae symptom but does not remove the cause.
