E Squared FlexLiner FG: The Ideal Fish Grade Pond Liner for a Thriving Aquatic Environment

A crucial component of any pond or water garden project is a reliable pond liner. Its primary purpose is to not only hold the water within the pond but also provide a safe and supportive environment for fish and plant life. Among the numerous options available in the market, E Squared FlexLiner FGTM stands out as an exceptional choice offering a unique combination of physical performance, buried soil resistance, and fish-friendly characteristics, making it an ideal solution for creating a thriving aquatic ecosystem.

  1. A Fish Grade Pond Liner Built for Excellence:

E Squared FlexLiner FGTM is a fish grade geomembrane designed to meet the highest standards of performance. Constructed with the proven strength and durability of standard reinforced Flexliner LLDPE, this pond liner offers superior toughness, high tensile strength, and puncture resistance, ensuring its longevity and reliability.


  1. Safety for Aquatic Life:

One of the key concerns when choosing a pond liner is its impact on fish and plant life. While some liners may pose risks due to plasticizer leaching, E Squared FlexLiner FGTM is formulated with special additives that are considered safe for fish (fish grade). These measures eliminate the need to compromise on the well-being of aquatic inhabitants while maintaining an affordable price point.

  1. Polyethylene: A Safe and Versatile Choice:

Polyethylene materials have proven to be fish and plant safe, without leaching harmful chemicals into the water. This, combined with its excellent chemical resistance and wide temperature range, makes polyethylene an ideal material for pond liners. However, it is essential to be cautious with general LLDPE liners that may have modifications with additives or coatings, potentially compromising their fish grade properties. E Squared FlexLiner FGTM stands out as a meticulously formulated liner, designed to support aquatic life while maintaining all the advantages of polyethylene.

  1. Certified Non-Toxic:

E Squared FlexLiner FGTM has undergone rigorous testing, including static acute toxicity tests with Vibrio fischeri, Pimephales promelas, and Daphnia magna. These tests have certified the liner to be nontoxic, ensuring the safety of the aquatic ecosystem it nurtures.
