This was the original tank I had for Flair. I took it back after a couple days because he did go down the tube, and I couldn't get him out. I was afraid he'd get stuck with the airstone there... I loved the lights on it though.
I find UGF to be quite dirty so I don't use them.....just one thing to think of because it'll make 100% water changes harder, and if you want to cycle the tank it'll collect tons of gunk under the gravel and cleaning it may mess up your cycle...not to mention being a pain.
DQ, if you're going to be doing 100% water changes anyway then I personally wouldn't bother with the UGF.
