I like the 'modern' look. Would the zinc and steel alloy pipes have rust issues over a saltwater tank (assuming that it would be over a salt tank)? I know they use zinc fittings on boat propellers so that wouldnt be an issue by itself, but with the steel alloy I'm not sure. I also see it uses stainless steel screws. If the other parts arent the same, then you have dis-similar metals in contact with each other in a humid environment which is the perfect recipe for corrosion.
Just something to consider....
