So I got a KZ nano kit on Black Friday for cheap just to try it out and I must say I did notice an improvement. I have been out for about a month and noticed my frogspawn hasn't been as extended as when I was using it. I was thinking about picking up some kz coral vitalizer. Anyone use any kz products if so what are your thoughts? I'm trying to promote growth and color with more than just good husbandry and good perams.
