The filter has been removed from this tank, as i think they look unsightly.

I will be using the background as a filter. Basicly it simply means drilling an inlet and outlet hole and filling the back with filtration media, usally sponge. The heater can be kept behind the background, as will the pump to draw the water through.
The holes are sealed with a fine mesh as to stop small fish and even fry from exploring.
Photo shows where the holes are drilled in the background:

The background is siliconed into place and left to cure for a few days. I've added a few beechwood branches to the aquascape. These are siliconed into place as to stop them floating once the tank is filled.
As you can see there is a gap of at least 2". This is filled with sponge and finally will be built up with rocks to hide the sponges.


The sand and rocks are yet to be added, also i wan't to add more twiggy looking branches to the setup.
