Why to choose fish safe pond liner?
The main difference between common liner and Fish-Safe pond liner is the formulation of ingredients. The use of one ingredient over another is determined by current market price of the ingredients. The pond liner needs to promote bacterial growth as a benefit to the pond. The use of fish safe liner in a pond that will house fish is a crap shoot that could get expensive, in more ways than one, if all your koi and goldfish get sick or even die. Tearing the pond apart and replacing with a fish-safe liner is going to cost much more than doing it right the first time.
