Most home centers carry only a small range of pond
supplies. For the best selection, visit a large garden center
or landscape supplier. To get acquainted with the vast array
of choices, go online and search for “pond supplies.” Here's
what you'll need:
EPDM rubber liner: Make sure the material is at least
45 mil thick. To estimate the size, add twice the depth of
the pond to the length and width. Then add 3 ft. to both the
length and the width. Finally, add the height of the waterfall
to the length.
Underlayment: This feltlike synthetic material provides a
protective cushion under the liner. Buy the same amount
of underlayment as liner.
Pump: Pumps are sized by the amount of water they can
move, measured in gallons per hour (gph). One way to
select the size is to plan on 100 gph for each inch of waterfall
width. We wanted a 5-in.-wide stream of falling water
and chose a 500-gph pump.
Miscellaneous: 12-in. waterfall tank, filter media, pump
basket, lava rock, black foam pond sealant, silicone caulk,
pea gravel, tubing and connectors sized for your pump.
Tip: Before you
shop for water
plants at a garden center,
browse online to learn about
your plant options. Just do a
search for “water plants.”
