Comments: This is my favorite Sword. "Melon Sword" I have grown this plant in light at 2w/gal and 3w/gal both tanks used 9325K GE CF. I just love the red leaves. As you can see the Melon Sword in the photo is crowded and out growing the 55gal tank it is in. The substrate in this tank is gravel with a little Flourite mix. I add 13-4-5 root tabs along with Iron tabs. Believe it or not, this plant has gone through two melt downs. It came back strong after I started to add potassium in the tank. I moved this plant to a 75gal. It out grew that tank too. I did a major leaf trimming and its growing strong now.
