I just got the plant. I don't add anything and dont Want to. I spent two years and to much money on trying to get plants to grow perfect with ferts, root tabs, liquid co2 and so on with no results. So I have a new plan...I just put them in and if they don't grow I get rid of them. I have the light on a timer for 8 hours a day. Anacharis, melon sword, cabomba, and wisteria are all growing great. I was just wondering if the dead leaves will prohibit new growth.
