Hello Everyone, Im having a small problem with my plants. I have a Lutea Crypt and Had a Banana sword, but they both have started dying all of a sudden. The Banana Sword just rotted away completely, so i got rid of it, and then a week later my huge Crypt started dying. The leaves on both appeared to just melt away and get holes in them. I fertilize with API Leaf zone and the tank is slightly over stocked so there is plenty of fish waste in the tank to feed the plants. Also, both these plants are established and have a very solid root structure. I also keep up on my fluorescent bulb changes, and both bulbs are 20 Watts in a 10 gallon so lighting should be good. Anyone have an idea to what the problem might be? They both were flourishing and then all of a sudden this happened. I also do 30% water changes twice a week due to the over stocking.
