I have 8 X 40 T8 over a 5ft -100gal, about 10in above...
Cover glass gets dirty fast and cleaning them constantly is a pain (the less 
maintenance one has to do the better)
I like having plants grow out the tank, right now the hygrophilia(quite a 
interesting smell), bacopa and a sword are blooming. I have a couple of 
non-aquatic plants growing on the back of the tank with their roots in the 
tank.
Yes, you lose light by having the lights a foot off the tank, I went to 8 
T8s instead of 6 and the tank is fine (I need a aquatic lawn mover)

lower it or buy more!
