i am treating my now barely swimming flameangel with copper. it says to test the tank four hours after the initial medication. i ran to my local lfs and they only had one type of test kit called FASTEST by aquarium systems. the gaguage on the tester is in mg/l of copper but the medication i have says to dose and remain at a level of 0.3ppm. see my proble. two different scales. is there a way of converting? the paracure. med says stay constant a 0.3ppm and the kit say stay constant at .15mg/l. what should i do. thanks flame
