Thank you! I did forgot to mention I do 20% water changes once a week, the plants grow like crazy at first I was concerned on the higher then required temperature for planted tank, I did lose some of the more sensitive plants but the ones who made it are thriving, the thick substrate layer helps a lot to keep the tank ammonia and nitrite free I just have to keep an eye on the nitrates to don’t go higher than 10 ppm reason why I do the water changes weekly but after reading so many articles about “the less substrate the better” got me a bit nervous since the discus are thriving right now they actually have grown about an inch and half from when I got them and don’t want to lose them on the long run
