Seachem Flourish Tabs compatibility with axolotls and other aquatic salamanders?

[John_Fillar]

Hey, I was wondering if anyone has experience using the plant growth stimulate tabs with their aquatic salamanders. The problem is that they are made with Copper (Cu) which I have heard can be poisonous to aquatic salamanders. Any help is very much appreciated.

seachem flourish also contains high levels of iron which can effect some salamander species.
