Hi all, just another update, the aquascape I will be creating will be natural bogwood but joint together using acrylic rods, I will drill into each bogwood that will be in a particular position then insert the acrylic rods to hold them in place. I do expect the wood to expand with water absorbtion however the rods are there so the wood don't fall or the fish don't knock them off. Next weekend the aquarium Manufacturers will have the overflow Comb for the weir and return pipe all plumbed in. Then I will be creating the aquascape and gradually fill the aquarium 6inches per day to allow a gradual settlement off its weight onto the polystyrene and floor.
