I have an 80gal tank setup with a hearty population of fish as well as plants. I'm loving the post by WyldFya, but I have some direct questions. First off is the setting. The tank is kept at a constant 79f, with a 2 inch sand substrate and 4 14" 10000k 55watt bulbs. The light is kept on for about 14 hours a day, give or take depending on when I get home. Currently growing, (starting with the out of control) Anachris(4" to 48" long), Chilensis(some rooted, some free floating), an Anubias Nana(slow growing), bamboo stalk(slow growing), and some Cobomba(just added recently, growing well. I started using a fertilizer about a week ago even though my plants were doing well. I figured the extra nutrients couldn't hurt. As I house a couple of Black Ghost Knives, I'm looking for a broad leaved, fast grower to aid in providing hiding spots. My first question is, for the plants I have, can I better arrange the situation to aid growth? The second question, Is there a fast growing, broad leaved plant that will grow well in the current environment? I'll be happy to attach pictures as soon as I'm able to get them back on my computer, and happy to answer any questions you might have for me. Thanks for the time.
