Fibreglass tanks are far less common than other types of tanks, however two advantages to fibreglass tanks is that they possess a reasonably high heat resistance and are quite inexpensive. That said, if one can find a local distributor, a limited range of shapes and sizes will be on offer.
When being manufactured, fibreglass tanks are made with a food-grade coating on their interior surface and are normally made in a manner that prevents sun light entering the tank. If sunlight makes it way to the water, then such allows algae to grow. Most fibreglass tanks are not recyclable.
