Low potassium question

How low is it?

I don't think here any data that shows raising potassium to NSW levels rapidly is a concern, but I suppose it might be. A different concern would be potential impurities in it if it is not a high purity additive.
 
Potassium 335 mg/l . I have red seas coral color B that is potassium and also contains Borax. I have low Boron also 2.86 mg/l . I haven't been using it, Iv had it for two years now. Red Sea recommends 1ml/100 liters so how much should I dose and how much per dose?
Thanks again.

I cannot say how much of the Red Sea product to use since it doesn't give concentrations in it.

I'd boost the potassium over a few days. If salinity is low, raise it first since the salinity rise will boost both of those.

For potassium, I'd just but a food grade potassium chloride product:
