Moon's Graden

My wife and I are planning a (big) pond for next spring. I missed the
discussion on the pond liners. I would like to do some research and would like
to know of any references or articles that discuss the possible hazards of
usinga roofing liner. The difference in cost would be significant.

I would also like to hear from people that have used the roofing liner and
find how successful they have been.

TIA

Hi-
Don't know anything about roofing liner, but can tell you
what NOT to use.  Last year I bought some industrial gradel
PVC liner material from a factory here in Houston (grey
in color).  Just to "test the water" so to speak, I put in a
few mosquito fish.  They were dead within 6 hours!  Then
I tried a couple feeder goldfish.  Dead within 8 hours.
But is there "pond grade" PVC???  I finally got polyurethane.
Very stiff but it works.
Cheers,
Bob (Houston)

Bob, your fish deaths were due to uncycled water, not the liner...
unless you did not rinse off the talc first.  The water needs time for a
bacterial colony to develop before adding fish.  I used roofing grade
liner, and while I lost a couple of fish early on, I discovered it was
due to my lack of patience in adding the fish.  Now, a year later, my
pond and fish are all healthy and mating like mad.  The dozen survivers
from last year multiplied to at least 50, and they are laying eggs all
over the pond.  Lots of plants will really help the process along.  

But, yes, there is pond grade liner.  It can be had from any pond supply
place... many are here on the net.  Most recommend a 45 ml thickness.  
Fish grade is usually guaranteed for the replacement of the liner, but
not for the replacement of the fish, plants and labor.  But hey!  That's
no small potatoes, eh?

Probably add additional plants next weekend and get the waterfall stream ready to go.
