question about bubble cloner

hello all, i recently made a bubble cloner much like this one except bigger, http://www.growkind.com/forum/showthread.php?t=34171, and had a few questions before i start taking cuttings. i have some clonex clone solution (not rooting hormone, its the liquid nutrient for clones and seedlings) and was wondering how much of that i should add per gallon of water. i also was wondering what the correct ph for getting clones to root is, thanks to all in advance

anyone know?
