Im reading alot that the lights would need to be raised, and definetly not a problem. I was going to use hairgrass for carpet, and some for background. Also staurogyne repens, oval ludwigia, lizards tail, eriocaulon parkeri, marsilea, and crypt.
Im using a T5dual odyssea on a 40b, and it puts out a good amount of light. With my 20L I want to go high tech, and led. Finnex fugeray seems like a good choice. Just wanting to make an informed decision.
