My advice is the same as those above. I ran a BC29 for over a year and liked it. I will say to watch out for detritus build up in the bottoms of the chambers. In the 1st chamber where the filter media is the screen floor is siliconed in and can be removed and replaced as needed to siphon the compartment. Under the bio-balls in the 2nd chamber is another false floor that needs to be removed to check for detritus build up and cleaned out. It is common belief that the bio-balls will eventually become a water issue problem, to combat that I would periodically take 1/2 of them out and clean them. It worked for me.
You will hear about several mods you can make to your tank. I recommend enjoying it for a while 1st. If you decide on a skimmer I would look into the Sapphire Aquatics skimmers as they are custom built to fit w/out modding the hood.
