I have a 250 Marineland DD in a wall... I love it, my wife loves it and the people who come over to the house, all love it.. There are some pros and cons.. However the pro's in my opinion, out weight the cons.
Pros:
- You can't get to the tank on the outside of the wall.. this means, nothing can go in it, people can't drop things in it.
- It looks clean and sleek, and it also helps cut down on the amount of noise the tank will make.
- My fish room is directly behind the tank so everything is accessible and in it's place without having to cram it all in a stand.
- My in-wall unit also has lots of plumbing that is hidden behind the wall.
- Easier to plumb and you end up having more space to work with.
- Your wife won't complain about the "mess"
Cons:
- You can't feed from the front.
- You won't want to paint the back of the tank as you won't be able to see in when performing maintenance (I use a large piece of painted cardboard that is gradient black up to blue - creates depth)
- Cleaning the front panel of the tank required a 2nd magnet cleaner as the wall doesn't provide easy access for a float magnet.
- Depending on how deep and how tall your tank is, you might have difficulty reaching the bottom of the tank, in the front (My tank is 3-feet deep and 28-inches tall, makes for a long reach when doing maintenance along the front, bottom of the tank.)
Hope this helps!
