Even if the water looks clear, it can be polluted. If the values are low, diseases or algae can start forming in the aquarium. For that reason, a healthy aquarium with near-natural conditions, it is important to check and adjust the water values regularly. For water analyses JBL offers advanced water tests as quick or colour change tests. These determine a specific value or several values simultaneously. They can be used to detect algae problems and negative nitrate, nitrite, potassium, magnesium values etc. In the JBL online laboratory you can enter the water values and receive an analysis of your values within seconds.
