Refugium in 24 nano?

[hermeez]

Has anybody tried to put a refugium on the back of these nano?
Does anybody have a DIY on this??

I've done it and it works pretty well, I used a 13 W PC on the rear of the tank, just cut away the backing and put the light right up on the glass, I used the 2nd chamber.
