I have results in
mg/l. Water tested 236
mg/l. Bottle says 1 ml in 25 gall equal 1.75
ppm k. So if I have 100 gall water in tank 1 ml raises
k 0.4
ppm. Is this correct? That meAns my tank needs over 200 ml of coral colors b by Red Sea if I want to go from 236
mg/l to a minimum of 350
mg/l. Any thoughts?
