Potassium deficiency?

[AverageWhiteBloke]

The level is so high you will never reach it. You never need to worry about metal toxicity.

What about the likes of copper built into most traces? I know you aren't a shrimp keeper and I'm not sure what levels shrimp will tolerate. Just wondering at what point copper might become an issue? I also hear that tannins/humic acids help keep metal toxicity down in soft water. I generally have almond and oak leaves in my softwater tanks hoping to prevent this.
