I have an old hydroponics type kit someone bought me years ago. Can these nutrients be safely used in an aquarium or am I better off using them for garden and greenhouse plants? It consists of two different containers that you add water to to make your solution. The pics show what is in each container plus the basic instructions to make the solution.

Hi all,

Unfortunately the bit you need to decide whether it aquarium safe is missing from the label, and it is how much of the total nitrogen (N) comprises ammonia. I'd probably save them for the garden/house plants.
