Hi!
I'm setting up my first aquarium, it is 240 litre (63 gallon). I have already installed a 3D background and put the canister filter intake tube behind it, the outflow tube will be in front of it. The background isn't glued to the back wall of my aquarium, there is open space behind it. I have made holes covered with mesh to the background to let the water behind it.
Now I started to put the gravel to the aquarium. As there is open space behind the background then could you say should I put the gravel also behind the 3D background? Or should I put the some gravel only in front of it and leave the space behind it empty? Is there any difference?
