Looks great.. the val should/will be fine with Low light. I had a broken light fixture for over a month and my val was the only plant that did well with just ambient light.
GREAT SETUP! Love the background and the décor. The flood light looks amazing in the tank. I'm not a fan of most DIY backgrounds or flood lights but this one is the exception
That really does look amazing! I have been saving some styrofoam to do something similar in my 180 gal turtle tank. Could you list how you did it and materials used?
