Ok I am setting up a 55 gallon tank and I am installing a 3d Pangea background.

I do not have a lot of experience with backgrounds, but I want to leave a bit of room for drawing water behind the background (and heater placement) and then discharging it to the aquarium side.

I assume that I want to drill some holes in the background to allow water to pass, and silicone some grills in the openings so fish cannot pass through? Is there some grills available that are small enough fry cannot pass through?

Also what filter would you recommend for this process? I think that a HOB is possibly out of the question? I am trying to design a cool display tank to upgrade from my 29 gallon so I am prepared to take some time and do it right, also spend a little extra if need be. I do not want any accessories showing (except maybe a thermometer).

Any help is appreciated, or pictures of set ups.

Thanks!

I would fill the background all the way or partially with bioballs or cut up sponges to provide room for biological filtration.

Ok I seen that on another site as well, if I do this would there be any need to take the sponges out and clean them?

If you cleaned them in other water it may clean the bacteria. You should never need to clean them.

If you fill the back of the BG with bioballs, where will the filter intake be placed and would you still need to make holes with grills?

You probably would in order to alllow adequate water flow. Maybe even a powerhead at one end if you are worried.

Pay attention to the depth of the backgrounds. The Rocky 3 and 4 models protrude up to 10", and that'll leave you 2-3" space at some areas.
