Fish and dry ferts
When I dose dry ferts (NPK or CSM+B), and they slowly drop into the tank, I notice that my fish take bites at them then spit them out. Once, I dissolved the frets in some water first then poured in the concentrated solution only to have my fish swimming around in the concentrated swirls looking for food.
Isn't either way toxic in those high doses to the fish? Is there a better way of doing it?
