We sell and recommend Firestone Pond Guard fish-safe liner. Made out of 45 mil. fish-safe rubber liner, Pond Guard is one of the most widely tested and trusted fish-safe liners on the market! Flexible liner is much easier to install than pre-formed ponds and features a longer manufacturer's warranty - 20 years! Roofing liner, though physically similar, may be treated with fish-toxic chemicals that do not easily wash off. Don't take a chance on the most critical component in your pond! 

Shipped ONLY to the lower 48 states!
