Ahmed, a 12V pump with a 10m head might be difficult to find.Thats about 3 storeys high.
When we used to keep a marine fish tank, we used to collect sea water from the OLD aquarium on the beachfront for free - without even removing the container from the vehicle. If you intend to fill up the tank in Dbn, it may be an option to investgate this at Ushaka as well?
