The Three Laws
Oh my. Oh dear.
Either the Pond Fairy has struck again
in the depths of the night, or you've just paid your local
landscaper a wad o' cash to combine the fatal, ineffable trio
of water, plants and fish in your very own back yard. You
need to know one incredibly important fact. It is central
to the entire hobby of water gardening.
THERE IS NO CURE.
Once
you have settled down at dusk by the side of your new pond
with a glass of fine wine in one hand and a great trashy novel
in the other, you become aware of a feeling you were not expecting.
No, it isn't inner peace and serenity. You need a Bhuddist
monastery for that, and you look lousy in saffron anyway.
It's not pride and satisfaction, either. That lasted just
about until you had to pull out and rinse off that mucky filter
pad on your submersible pump, and discovered one of those
expensive fish the landscaper sold you dead in the skimmer
looking like a live grenade. No, what you are feeling is the
common malaise and unrest that all ponders feel once their
current water feature is installed, paid for and running.
It is the eerie and ominous, all-pervasive psychic effect
of the Three Laws to which you are now, like all other water
gardeners, frog fanciers and koi keepers, immutably subject.
You find yourself looking at that prize rose bed and reflecting
that it's getting really tough to keep up with those darn
Japanese beetles every year. The lawn is just too much trouble
to keep groomed. Those annual beds are just so
tacky,
somehow. Wouldn't a perennial bed be easier? Maybe a more
natural setting, with bombproof aquatics and blooming marginals?
You find yourself looking at every home you visit and saying
to yourself : " I'd put the pond
there!". Well,
bucko, once The Laws have you, there is no escape, so you
might as well know what you are dealing with.
The First Law:
There Is Always A Better Fish.
Yes, I know your original intent
was to build a lovely, low-maintenance water feature with
a minimum of critters to worry about, but that baby koi at
the fish show was so cute and he really isn't all that big.
Surely the filter mat and lava rock will be able to handle
the load. Oh! Look at that 2 year old fish on this website
we
need something to eat all those mosquito larvae, anyway.
And
so it goes. Pond people are natural enthusiasts and incurable
optimists. The pond just isn't right somehow without something
to come wriggling up to the surface when you shake the can
of fish food. It's real easy to get overpopulated. And fish
grow. Fast. Real fast. Which leads us naturally to
The Second Law:
There Is Always A Better Filter.
Shortly after buying your umpteenth
fish and introducing him into the pond, you realize that the
population does not look happy. They are sulky and lethargic.
They are not eating and they look unhappy. If you are smart
and thinking ahead, you have already bought a good test kit
for ammonia and nitrite, and have just found that your pond
scores high on both. That lava rock at the top of the falls
just isn't doing it, folks, so it's time to do your research.
There is an answer for every filtration problem, even if you
didn't know that the question even existed. It is important
to understand that there are three kinds of filters (chemical,
mechanical and biological) and each has its place in The Great
Swamp of Ponding.
Chemical filters
(charcoal, zeolite and the like) remove chemical impurities
and pollutants from the water by binding them to their own
chemical structure. They are usually used in short-term or
emergency situations, such as sales or show vats, but have
no place in the outdoor pond. Most water gardens and koi ponds
combine mechanical and bio-conversion filtration in one or
more containers of varied design. Pond filtration is one of
the most rapidly developing and hotly debated aspects of the
hobby. Gravity-fed vs. pressurized. To UV or not to UV. Lava
rock or Siporax ( or Tuffy sponges?). The choices are endless,
and what may have worked for Cousin Earl in his 25,000 gallon
indoor showplace will be a gurgling disaster in your 550 gallon
stream and pool.
The solution is
to ask questions, and never entirely believe any of the answers
until you have seen them work. Find other hobbyists (look
for gardening clubs, hobbyist websites like this one (gasp!),
koi clubs) and pick their brains. Don't be shy. Any experienced
water gardener and koi fancier has been where you are right
now, has done the fix, bought the t-shirt, and then used it
to plug the leak in the hose that was supposed to be leakproof.
Describe what you've got in a gathering of pond people, and
you'll hit 14 "bore-buttons" simultaneously. Ponders
love to talk, especially about their disasters and how they
fixed them. Your solution is Out There.
A caveat, if you
will, before going on. Never believe a filter manufacturer
when he tells you what the "capacity" of his filter
is. For the safety of your critters (which become family members
very quickly), cut the claims by half, and install accordingly.
Your goal in filtration is to expose every molecule of water
in your pond to your bio-converter at least once an hour.
Make sure your pump is up to the strain and your filter and
piping can handle the flow.
Oh, too much splash?
Fish growing fast? No room for that lily or lotus? Ah, Grasshopper,
you have just run afoul of
The Third Law:
There Is Never Enough Water.
Almost every
water gardener starts small, thinking that small size means
low maintenance. This is not entirely true. A pond that is
shallow will be more susceptible to wide shifts in temperature,
and is more subject to catastrophic reactions to pollutants
and other toxic events, especially with high fish populations.
Ask any ponder; almost without exception, he or she will tell
you that the showplace you are viewing in her idyllic back
yard is actually the fifth pond on that site (if you count
the two water lilies in the muck bucket!), and if they had
really been thinking during construction, they would have
dug down another foot, at least.
A true pond
owner is eternally greedy for gallonage. Big volumes give
you stability and room for fish and plants, and if designed
right, also can be made routinely almost (note the word "almost",
it's a killer!) self-maintaining. Ponds are very much like
model railroad layouts. There is generally at least one glitch
needing repair, and there is always one more improvement that
will make it just perfect. If a boat is a hole in the water
that you pour money into, you can achieve the same sense of
accomplishment with a pond, which is a hole in your yard full
of water that you pour money into. Your chances of drowning
with a pond are marginally smaller, and you don't have to
travel to do it! A true ponder will tell you that if you are
still mowing grass, you do not have enough pond.
Never be
afraid to look at your current water garden and envision change.
It is what this hobby is all about. See you at the next koi
show!
