Fishkeeping - Using Roofing EPDM for liner

Ditto here. The liner in my pond, supplied by next door neighbor (roofer by
trade) bears the EXACT same brand-name markings and trademarks as the "pond
liner" being sold at outrageous prices locally. I have received no
complaints from the fish, either.

I disagree with this. I've used Firestone roofing liner (45 ml) without
even rinsing it, and have had NO problems. I know of 6 other ppl in my
area
that have done the same, without a problem. The only difference in the
liner is the stamp on the back...."Pond Guard"
Why pay .50 cents more/sq.ft. just for the stamp ?????

Yes, the EPDM liner from roofing companies is cheap for ponds, but I
refuse to use it in my installation for customers simply because I
cannot warranty it the way I can the EPDM sold for ponds. You mentioned
the rinsing and scrubbing process and this is ABSOLUTELY necessary - the
roofing EPDM is often coated or impregnated with an algae inhibitor
which is extremely toxic to fish and aquatic plants.

Ideally, plants go into a new pond after dechlorinating the water, fish
and scavengers go into the pond 2-3 weeks later. This info comes from a
very reputable fish hatchery that I've done business with for many
years.

I've seen do-it-yourselfers use everything from kiddie pools to old
swimming pool liners for their ponds - in many cases this works out just
fine and in some cases time and money will be spent later on to do it
the right way!! When your budget permits, I vote for doing in the right
way the first time.
