I have been testing both of my tanks using Salifert K test kit over the last few weeks. It is consistently showing K at 340-350. I am considering starting to does some K. How much should I look at adding and which brand would you use? I do not need any more nitrates so I am looking for something without them.
For reference, one tank is 130 gallons and the other is 32.
