I've been using it for a while now, the colors do not come out as great as they do with omega. I bought the little 3oz bottle and used it for a few months. The colors on my lab and pseudo seemed to fade. I have since switched back to both flakes and omega one. My fish have forgotten how to eat flakes that rest ontop of the water. My filter has been broken for about 3 months now so i am stuck on water changes every 4-5 days.
