If you want a 55g.....get a 75g instead.
Wider is better.....the 55g tanks are just too narrow. (I have 2)
You could use a pressurized system on more than one tank.
Ask for a manifold with the system....
I just have a new camera on my list, but its mostly for taking aquarium pics.
I bought myself a 40 breeder with bday money, so I'm quite excited about that.
