The pond was started in April of 2002, with plants and fish
added in May. Volume is approximately 900 gallons, as determined by fill
rate. Filtration and aeration are provided by a 900 gph Diamond pump and
32 gallon DIY biofilter. The biofilter is an upflow construction in a
Rubbermaid trashcan, with a 6" settling area at the bottom, lava rock, and
one box of Spring Flo filter media. Two layers of polyester quilt batting
are placed above the Spring Flo at the start of the ponding season to
remove the sediment and sludge that accumulates until the pond is shaded
enough to slow algae growth. This year, all the water hyacinths have been
moved to the top of the biofilter. Last year, we used begonia and coleus
in the top of the filter, with moderate success. The water is returned to
the pond via a 3' falls.
Current inhabitants include two 7-8" koi,
five 7-8" shubunkins, two calico fantails (ranging in size from 3-4"), a
gold fantail, a black moor, two sarassa comets, and more than 20 common
goldfish and goldfish/shubunkin mixes (newly hatched fry to 6" adults).
We've introduced a variety of plants, with emphasis on those that are
winter hardy in zone 6. The current flora includes lizard tail, chameleon
plant, miniature and standard cat tails, miniature horsetails, Queen
Victoria lobelia, blue flag, Longwood hybrid canna, blue pickerel rush,
pennywort, creeping jenny, Burgundy Princess hardy lily, an unnamed yellow
lily and arrowhead plant. A few of the plants require replacement each
season, or overwintering indoors: water hyacinths, water lettuce, Texas
Shell Pink tropical lily, Black Magic Taro, parrot's feather and water
poppy. The trickle tower was added during mid-summer of 2002, and it
works, even though it's ugly.
As you can see from the photos, the
landscaping around the pond isn't finished. We've yet to put in a
permanent GFI outlet for the pump(s) and a rock garden to the right of the
lotus bog, which was added following the waterfall reconstruction in
summer 2003. Always a work in progress!
