What range should potassium be in. I believe 400 is sea water but what’s a high and low for sps?

I do not know for SPS but in my experiences concentration above 550 mg/L can be toxic for both fish and CUC. in my old aquarium my concentrations rise to just above this level - followed by a mass killing of my fish and CUC. However - my corals has never looks as nice as they did with this high levels. I have heard of similar events from other aquarists. I can´t say for sure that it was just the potassium concentrations (and only them) that was responsible for the killings but everything indicate this.What range should potassium be in.
