Yep, this is the entire filter, and it is built into the tank. There are no holes in it. My best guess is that it draws water in where you see the grates. The grates don't actually open. Instead it seems to have a very small gab between the front wall, and the box. I guess it draws water down there there, into the first box, then to the second box, and from there to the tank. Pretty darn complicated.
Based on what you see do you think I would be better off just using a canister filter? I guess I could use the box for the input/output of the canister.
I just hate the idea of spending a couple hundred on a new filter if I can get this one to work well.
