All the ornamental plant fertilisers already mentioned contain copper, which is usual in good trace element fertilisers for aquariums. Copper is an essential trace element for plants and animals. _x000D_ _x000D_ For shrimps, other decapods and some other animal groups copper is a central atom of the blood pigment haemocyanin, and thus essential for transporting oxygen inside the animal. _x000D_ _x000D_ The concentration in JBL PROFLORA FERROPOL, JBL PROFLORA FERROPOL 24 und JBL ProScape Fe +Microelements is so designed that all trace elements are available in the required quantities. Not even multiple fertiliser overdosing can harm the shrimps and other decapods.
The colouring of Ferropol depends on the pH value. During production Ferropol is set to a pH of 4.5. Then the colour is olive green. During longer storage and especially when the bottle has been opened, oxygen from the air gradually penetrates the fertiliser, the pH rises and changes the colour towards a brown tone. _x000D_ _x000D_ This has no influence on the effectiveness of the fertiliser and its ingredients. You can safely continue to use it.
