I've always had HOB filters so I've no experience with canister filters.

I'm trying to determine how much space is required between the tank and the wall to run the output/input lines. Would the plumbing for a canister be less then the +/- 4 inches a HOB would take up?

I'm trying to find a system that will keep the amount of space the tank has to sit out from the wall to a minimum (without drilling my tank, of course). Any suggestions?
 
the space behind the tank needed is really very small much less than a HOB filter maybe a 1 1/2 -2 inches would be what you need.
 
i just moved one of my tanks to another wall in my living room and all that is needed behind is a max of 2 inches, depending on what size tubing you have for your canister.
 
I would leave 2" for the tubing, as measuring from the wall to the cabinet exterior. Most canisters will use disconnect valves or a valve block. Not only do you want to accommodate the hoses, but the supply/return hardware or the disconnects for when you will eventually have to remove them for cleaning.
 
Bob, you are so correct in that, lol. at my old apartment i set my tank and canister up before filling the tank and had just enough clearance behind the stand for the hoses (they were snug against the wall) and when it came time to tear down the tank and move it to my new place it was an absolute bear to get the hose assembly out!
 
Having many different type filters for different purposes I found that leaving 5" spacing not only allows for a change in filter types like a wet/dry overflow box or HOB converted for nitrate filtration, but also arm room for reaching behind to thread cords or cleaning glass.

I recommend that even though you are going to a canister filter with small hoses you maintain enough room to fit your largest HOB or overflow box for future use, special applications, or backup filtration
