Hi Chris, this is normal as it can take 6 weeks to cycle a tank. The best way to cycle a tank for discus is by doing a fishless cycle as you avoid contamination from other fish, plants this way. I would suggest you start in the beginner section with the stickies. Start with the video in this one, long but well worth your time http://forum.simplydiscus.com/showth...CH-THIS-VIDEO!.
