Bryan thats a great question but I suspect the thing that would age them most is ultra violet rays. Salt water on food grade plastic isn't much of a concern IMHO. Besides if it does get brittle it isn't like you need to budget for a new one.
I was thinking of using one as a DSB refugium, so it's not the cost of replacing, but the disruption in the sandbed if I had to replace it.
