most of the wc that have come in have been in good shape, so If you know you are getting wc and dont mind and are prepared to deal with any issues than go for it.
In a tank that small kill the water feature, just not a good idea IMO. when i first had mine in that tub with the false bottom the only direct lighting came in from the vent that was 7'' by 7'' in the lid. there was a light strip above it with t8 4 foot bulbs that I use for the rest of my racks other than that ambiant light from the room. I only have pothos in my toad tank so light is not an issue.

I'll go snap a picture of the new setup quick and post it here for you.
