Not sure what type of calmag you are using, read the directions on the back they should tell you how many ml/gal you need, don't use too much epsom salt, it can cause salt build up, good luck.Cheers I've been adding 1ml/1L of calmag and recently started adding Epsom salts...but no idea how much to use so I've just mixed two scoops (using plastic top off gellette shaving foan) and shook it up in to the mix...how much salts should I add to the mix using a pint glass as a gauge measurement?
