Tank cycle is almost complete...its right at 1.0 and thats after about the 6 minute mark, usually after about a minute its dark green. I went on vacation, but before I did I made a 50% water change because since I was going to be gone a while. My brother called me and said the tank was cloudy and couldnt see the fish, made me nervous because I was 8 hours away hunting in Michigan. But all the fish were fine, I'm assuming the tank was doing its thing cycling. Im getting ready to do a small water change and tested it before I did. Cant wait till its done so I can add the rays
