JBL ProAquaTest Fe - Iron, Refill

The JBL ProAqua Test Fe is a water test for the analysis of the optimal iron value in freshwater and seawater aquariums, as well as in the pond.

Iron is a trace element indispensable for plant and animal organisms. In addition to a sufficient supply of CO2 and other trace elements, iron is crucial for good plant growth and is consumed continuously. Glassy yellowish staining in young leaf shoots and younger leaves are a sign of iron deficiency. Iron and some other trace elements are only stable in the water for a limited time, even if they are bound to so-called chelators, as is customary in modern fertilizer preparations. In addition, supplied tap water is usually iron-free. Therefore, the iron content must be monitored by a regular check with this test and re-fertilised. For a good plant growth already a concentration of 0.1-0.2 mg / l is sufficient. Values of up to 0.6 mg / l may be useful in very densely planted aquariums. In seawater, values up to 0.05 mg / l are recommended.

Stagnant plant problems or inexplicable green algae can be easily remedied or prevented if you keep track of the iron values!
