Are fertilizers harmful for shrimps?
Since I have a fan shrimp in my aquarium and these animals are very sensitive to copper: Do your iron fertilizers sera florena and sera florenette also contain copper?
they contain only such minimal traces of copper that there is no danger even for very sensitive shrimps and other invertebrates. sera florena and sera florenette are frequently and regularly used also in shrimp tanks without any problems.
Are these fertilizers in any other way harmful for my shrimp?
No, you do not have to fear anything.
