My potassium levels are always low. It is one I don't have a test for but I send samples to a lab in Colorado accasionally just to check myself. Currently it is 85.8 mg/l. The dosing chart on the bottle doesn't make much since. It says 1 ml will raise 25 gall 1.75 ppm k. I have a 110 reef with a thirty gall sump. I just call it 110 gall. That means 1 ml will raise my k level only .4. If this is correct then I would need the whole bottle and I know better!!
