I saw some of these totes/tanks that are made by fiberglass.
They are stronger than the normal plastic though I have never used them before.
They are good as fish ponds for fish like Guppies, Koi, Goldfish, etc..
If I'm not wrong, some of these fiber glass tanks are now being used even in the bathrooms.
Some fiber glass tanks even have a window but will be more expensive.
Keep some fast growing plants to absorb any toxic(if there is) but I'm not sure how effective.
