GH+ increases the total hardness of the water (mineral salts). The optimum GH lies between 10 and 20°A or higher. Rainwater lowers the GH. A value that is too low is detrimental to filtration and to the development of plants and fish. Regularly check the GH, especially after heavy rainfall and in periods of drought. Correct if necessary. Due to its composition, GH+ favours filtration, mineralization vases and water clarification. Contains an extract mineral naturally rich in trace elements.
Composition : Mineral salts and trace elements.
Directions for use : Shake well before each use. Spread over all the water surface (do not dilute beforehand). Proceed in small quantities by waiting at least 24 hours between two treatments and checking the GH and pH each time.
Dosage: One measure or 25 gr per m3 of water raises the GH by 1 to 2 units (dosage indicative to be adapted according to circumstances). A packaging allows to carry out 4 to 8 treatments of the indicated volume.
Storage: Store in a dry place between 10 and 25°C. Under normal storage conditions, the product has a shelf life of two years.
