Wicked ato! need help though

[ScubaSteve]

Plastic bags or a good quality spray plastic liner would works. I once used a spray plastic to waterproof an experiemnt that is WAAAAAAAY more sensitive to leached chemicals than an aquarium and it worked fine but I had to look around. I can't find the dealer I got it from right now but will let you know when I do. I remember is was food-safe/food-grade liner. Try googling that?
