Hey guys, I'm currently cycling my second tank. I've gone fishless this time. I was given bad advice by the guys at the pet store last time but have since joined this forum and now know better. The tank has been cycling for about 10 days and it's not converting major amounts of ammonia yet, probably about 1ppm a day. I've been topping up and keeping the ammonia level at 4ppm. What's confusing me is, my nitrites are completely off the chart and I don't know if I should be leaving it alone now or doing a water change. Will the high nitrites mess the cycle up. This has been so much quicker than the last time round and I'm hopeful the tank will cycle with no issues. Any help you guys can give me would be brill. Thanks
