Answer 1

Fiberglass is fine but in the US most tanks and other items in contact with the water are sealed with gel coat, a white (generally) opaque coating of resin that seals the fiberglass and helps to keep water out of the fiber matrix.

If your plan is to export, check regulations on what are approved materials to use, some items will not be acceptable. Fiberglass with or without gel coat is not a problem.

Other materials are as good or better and may be cheaper to use like polyethylene. Take a look around.
