How do fiberglass tanks differ from plastic tanks or poly tanks?
A. Fiberglass tanks are made differently from plastic tanks or poly tanks. Polypropylene plastic tanks are homogeneous;. The homogeneity of polypropylene plastic tanks protects against chemical attack if the plastic tanks are scratched or gouged. Fiberglass tanks are laminated, and can de-laminate over time. If fiberglass tanks are scratched or gouged, chemical attack can occur.
