my old 90 the silicone looked like crap, covered in algae and almost looks like the algae was eating away at it slowly, it was less then 10 years old. It just looked horrid, but it held water just fine. Yet I've seen older tanks with silicone in much nicer condition.... My 90 was covered in hardwater stains from cichlids, I would imagine salt would do the same number on silicone as alkaline freshwater?
Double Deeps look awesome, but I struggle to clean and move stuff around in a tank that's 18 front to back and 24 high.... My armpits get wet and my tshirt gets soaked.... Id hate to have to do anything in a double deep haha.
