I currently have this tank. http://www.amazon.com/gp/product/B00...ls_o01_s00_i00
and I think the LED lighting is not sufficient for the plants. My anubias on lava rock, is yellowing now, but the hornwort is doing well since it's floating at the top, the cabomba is doing pretty well, although some leaves look like they're "melting". I just don't know what else it could be. the parameters are great. I was wondering if anyone else has this type of tank, and if they had similar problems, and how they fixed it. My husband won't allow me to get a new tank yet, and asked if we could just change the light. Any suggestions are welcomed and appreciated. Thanks!
