With my experience with discus i quickly realized that i started to care so much for them that i sacrificed a lot of my existing tank. I eventually cleared out all my denisonii barbs angels and clown loaches just so they could get a decent amount of food.
Obviously the planted tank is something everyone wants to achieve but after raising discus to be adults i can say that if i were to do it again theres no doubt that i would skip all the hassle and just go barebottom until they are adults. I had a fairly good amount of plants and soon saw the hassle everyone on simplydiscus was talking about that ignored. It'll save you so much work its not even funny! Not trying to discourage you from giving them an awesome planted home but it is without doubt a whole lot easier. Of course this depends on the size of the discus you want to get
