I think Luis Navaro has one, Ghazanfar... I've sold over 50 of them in the last few months. Most of those I remember are using small stem plants like micranthemoides and petite nana, things along that line. I don't know of anyone who has tried macrandra in that tank. You may be interested to know that JBJ is going to release a model later this year with two 24 watt PCs. That should be more than enough light for anything.
