Please add the required dosage of JBL Clearol to an aquarium area with sufficient water movement. This enables a fast and even distribution. We strongly recommend you check the pH and KH values of your aquarium water before use, since Clearol may only be used with pH values above 6 and with KH values above 5° dKH (see label). Otherwise there is the risk of a sharp drop in pH.
The active ingredient in JBL Clearol does not cause the gills of fish to stick together. However, the extent to which the precipitating substances are deposited on the surface of the gills is another issue. JBL Clearol does not change the oxygen content in the water.
Clearol always acts immediately. The cloudy particles are bound by flocculation and sink to the bottom. However, if there are too many particles or if the cloudiness is due to another cause, Clearol will not be effective.
Regular application, e.g. at weekly intervals, is not advisable here and can even be counterproductive, as the active ingredient accumulates in the aquarium and a sharp drop in pH can occur if the KH and pH are not correct. If the cloudiness does not disappear within three days, we recommend the use of a UV-C clarifier such as JBL PROCRISTAL UV-C Compact plus 11 W
