When I build the stand for the new tank, is there anything wrong with enclosing the back of the stand with plywood. I will be using LED lighting over the new tank so heat shouldn't be an issue. I was thinking that humidity build up in the enclosed area might be though. The stand I have for my 125g is open in the back and I have half of the back closed with a piece of acrylic to keep salt creep off of the wall.
