Potassium levels

[KRAUSE]

I would like to know what level people are keeping their potassium at. I have heard of people increasing the amount (up to 2x the natural amount) to obtain better coloration and growth in an sps reef. Thanks in advance

It should be over 400ppm I believe. I run mine around 450 ppm. Alot of people will say that adding potassium is not necessary though. I use Red Sea low nutrient system, so I check my levels occasionally due to depletion issues.

I keep mine @ 400, I don't know if higher is bad but lower is not good
