Water gardening is easy! And fun. It brings in lots of wildlife, gives you muck to add to the compost pile when you do the big spring clean-out, and adds a touch of serenity to your landscape. Want a goldfish pond for your yard? It's as easy as going to Tractor Supply or your local feed store, buying a galvanized horse trough, and filling with water. Voila! Insta-Pond!
Besides being easy to set up, horse-trough ponds are portable. This is handy if you're renting ~ you can just empty it, put the fish in a bucket and plants in garbage bags to contain the wetness, and off you go.
As with anything new you learn, there is a learning curve. But if you follow this advice above all else ~ LOTS of plants, few fish ~ you'll do fine.
Materials and price list ~ everything here varies so much, so these are only guesstimates:
Horse trough ~ 2'x2'x4' long ............................. $100 or so
You may find one cheaper on Craigslist. BTW, mine are 2'x2'x6' and 2'x8'-round. They're bigger, so will be more expensive, but the bigger the pond, the more plants and fish you can have. Get the size you want. It'll be worth it since it'll last ten-plus years.
Plants and pots ane bricks...................................$50?
This varies so much that it's hard to say for sure, but you should be able to get plenty of plants for fifty bucks. And if you know a friend who has a pond, they'll likely give you plenty of starts for free. Cinder blocks and bricks are cheap. And surely you have pots laying around...
Fish ........................................................................ $1
Seriously, only a buck. Just get a couple feeder goldfish at PetSmart. They're only 25 cents. You can go more expensive with fancy goldfish if you want, but I'd advise against koi unless you get a BIG tank.

Hose to Float Valve ............................................... $20
This is entirely optional, but if you put your pond in an out-of-the-way spot, like in your backyard where you only visit it on weekends, it's a good idea to keep a constant level for wildlife.
Water treatment ................................................... $10?
If you have chlorinated water, you'll need to treat it before adding fish and plants. Since I have well water and don't use the stuff to treat it, I have no idea how much it'll cost.
Fish Food ................................................................ $10
Get the floating kind so you can easily fish it out if you overfeed. Plus, it's nice to see the fish come to the top to get it. Ten bucks will get you enough to last years for just a couple fish.
Some more thoughts...
|Float valve (automatic water refiller).
Speaking of potting those plants, you don't have to just use ugly old plastic ones. Those work best for lilies since you're just going to sink the pot to the bottom of the pond. But for margnials and bog plants, ones that grow out of the water, you can put them in a pretty pot and set it up on bricks and blocks so that it shows out of the water. Many marginal plants and bog plants actually grow better that way than the traditional way ~ setting the pot low enough that water covers the rim.
|Yummy icky stuff for the compost pile!
A note about fish: I know those koi are gorgeous, especially those gold ogon butterfly ones, but don't get them unless you buy a BIG trough. They may be small now, but they grow fast, and man can they get big. They need a lot of room to swim enough to stay healthy, and they create a lot of waste which can make them stressed and sick (and even kill them), so it's really inhumane to keep them in a small pond.
And when cleaning out the pond, don't take the word "cleaning" too literally. Just get rid of the much at the bottom. You don't want to scrub the sides. That slime on there is really colonies of beneficial bacteria, the ones I mentioned before that clean out the fish poop. If you scrub the sides and remove the bacteria, you'll likely experience an algae bloom while waiting for those bacteria to grow back. No one likes pea soup in a pond. Ick.
Now I'm off to shop for a water lily and some more fish! And maybe a little fountain set-up. And a bird bath specifically for the ponds. And...
Here's what the new large tank pond looks like a week or so later.
This is NORMAL and will clear up on it's own over time.
At the same time, the existing tank that I'd just cleaned out and moved was a lot clearer, though not completely clear. The difference in water clarity is because of those beneficial bacteria I told you about earlier. The smaller, older tank had a full colony of them all over the sides of the tank, so when I drained it, got the goop off the bottom, set it back up and refilled it, the bacteria were already there, and started filtering and changing nutrients right away. They did take a bit of a hit because of the draining, removing old bricks (I should have put the same ones back in, but didn't), and refilling, so the water wasn't completely clear. But it was a lot clearer than the new big tank.
The new pond doesn't have those colonies of bacteria all over the sides of the tank, so any nutrients in the water don't get changed into plant food. They're still there, in the form of "bacteria food" which happens to be the same form algae likes, hence the algae bloom. (Another reason for the algae bloom is all the sun hitting the water.)
Given time, those bacteria will colonize the sides and all other surfaces under the water and the water will start to clear (Also, once I get some lilies and more plants in there, they'll grow in and start shading the water to block that aforementioned sun, and the algae will lessen even more.). That's one reason for the chunk of plants floating in there ~ to inoculate the water with those bacteria and give them a jump start (and because I didn't have time to repot them ;).
Don't worry if you don't have anything to inoculate the water with. If you can find it at a water garden nursery, you can buy a bottle of "bacteria starter" or "filter starter", a liquid (usually) that contains these beneficial bacteria. Or you can just let nature take it's course. I like letting nature do it. Cheaper and easier.
I also plan to gather up all the shards of broken clay pots, put them in a big plastic pot or basket, and sink them in the big pond. The broken ones that are still mostly whole I'll put in there in such a way that they form "caves" for the fish to hide in. This will add more surface area for more bacteria. Since the big pond is the koi pond and they poop a lot (A LOT), that will help things in there. And gives me a use for all those broken pots!
