We're thinking of getting a 140 gallon fiberglass tank and were wondering if anyone had experience using them for RES or even fish. From our research it seems like fiberglass is very safe in terms of leaching, since it's used for coy ponds, fish hatchery tanks, aquarium decorations, water storage, outdoor pools -- you name it. This tank has a coating on it called gelcoat which is molecularly bonded with the fibreglass and is apparently supposed to prevent leaching.
We got interested in the fiberglass option when looking for a "once and for all" home for our RES big enough never to have to be replaced and easy to transport when we move. This is less than half the price of a similarly sized glass aquariums and a fraction of the weight, without the risk of breakage. So does anyone know anything about it?
