Hi there. For sale I have a 4-2-2 Aqua medic Percula marine aquarium. It has a built in sump on the back. Comes with skimmer, stand and a few pumps. Needs a bit of a clean. No scratches as far as i can see. would be ideal in a wall with the rear sump. Very heavy good quality tank so will need 2 strong men to carry. Thanks for looking. Call on 07413557247
