Pond / Watergarden Science

Would you like to exert god-like control over an environment and its resources? Well, you should get a pond.

By adding even a small watergarden to your property, you can learn lots about the fragile balance of a vital ecosystem. To ensure a healthy biodiversity, you will need to monitor and manage many different variables.

Over time you will also develop positive personality traits like humility and patience, since nature works on its own timetable and to its own set of priorities.

Owning a pond can be a lot of work, but extremely rewarding.

Step 1 Lesson 1 - Biodiversity / Pond Residents

Once you add a pond or water feature to your property, you will be amazed at how quickly you become the popular neighborhood hot spot for critters. Everybody loves water.

However, with great gifts comes great responsibility. If you invite all of these creatures to your house, you'd better be ready to be a good host.

Can any one help me out ,i need to know that as i have the turbine system (plant) which releases Co2 at the rate of 1932.3kg/hr and i need to consume that Co2 with the help of Algae in pond just like as the Raceway ponds do ...i have all the specific industrialized land area to construct the pond and to perform this task i just need to have the specific size of the pond system which can consume 1932.3kg/hr of Co2 so that i can perform it on the large scale project with minimum cost involved for example " http://www.ems.psu.edu/~elsworth/courses/egee580/Utilization_final_report.pdf " ...... you can take a look at that pdf file on page number 9 figure 2.1.4 ,i just need to have the minimum area to make that pond including the calculation of all the dimension and all including minimum cost ....but the main focus here is the calculation of the pond area , i just need to have the total area of pond (sizing and dimension) (length,width,depth and all)which can perform this task of consuming Co2 at rate of 1932.3kg/hr with the help of Algae.........i am in great confusion with my calculations and i need help can you please help me out in performing the calculation work and finding out the specific area needed......i wiil be really very thank full to you...........Have a Good Day

I am the "Frog Whisperer", so my wife and daughter say! I have adopted a big "Green Frog" male. He croaks back to me when he hears my voice. I can get him to respond whenever I want. Its fun! Except now he has found our bedroom window and lets out small barking croaks all night ! Then in the morning I make coffee, then go out and scrape the wood chips in my Organic Garden and capture a few earthworms. He gobbles them up. Then meditates for a while, before croaking to me again. Pretty cool. I just hope he remember to hibernate this winter! He is living in a blue half of a 55 gallon drum I salvaged for tub gardens. Some I keep full of rain water to water the plants in the others that I filled with dirt. I have about eight with various herbs and plants in them.Peppermint, chinese squash vine, anise, pumpkins, irises, and more. Its fun and relaxing to water & weed. And the frog is more fun! I also have three Koi in one tub, with submerged planters filled with Cattails, irises, and Arrowroots (all scrounged from local lakes and swamps). See my instructable "Frog Whisperer" Yours is a Great instructable too! Thanks for enlightening newbees to the pond world. Enjoy, seek peace, Triumphman.

Great frog photos. :) We put a pond in last summer and the frogs alone are great entertainment. lol

[nguoidanbadep]

 Oh my God, this is so interesting. You must be so proud. I am slowly building a pond myself, will definitely want to have something like this. Thanks for sharing this.

[DragonX777]

We builted a backyard pond before at Washington state, and suddenly we have frogs in our backyard pond. We even hear them croaking at night.

[ladyfromthecoast]

Hi again.With regards the ponds mentioned - the smaller one is only about 6 - 8 inches deep in places. In the summer it evaporates quickly (especially when we are not there although someone tops it up for us). We were thinking of building some sort of decking over the top of part of it which would shelter the fish and also (hopefully) stop some evaporation. Don't want to plant trees 'cos as Babair said, leaves will cause build up & we have enough of that now. This seemed the better option. Does anyone know if this will help?

[ladyfromthecoast]

Hi. Found this site and wanted to join as you guys seem to know your stuff. Bought a house in South West France and inherited 2 ponds (one converted from a huge round pool - must be about 6 feet deep). Frogs by the dozen (really noisy in spring) although great 'guard frogs'!! And fish.... can't stop them breeding. Must have around 300 last years babies in the big pond. I put some weed from the smaller pond into the bigger one - BIG mistake as it gave the babes somewhere to hide. I guess the pond will only sustain what it can. Does anyone know where I could re-home some fish though (near Cordes-sur-ciel SW France) Thanks.

[Wasagi]

 AMAZING! Your pond is huge, to begin with. And did you have to add frogs, or did they just appear? Great instructable, five stars!

[Bitsi]

 THANKS.

The pond is approximately 20'x20' . I hired a fellow with a backhoe to excavate it.  The deepest part is about 3' deep, and there are a couple of shallower shelves for marginal plants.  The edges are designed to discourage herons and raccoons from fishing.

No, I didn't have to "add frogs".  It was sort of amazing the way that they just showed up as soon as I put water in the hole.  Before I put in rocks, or plants or fish, the frogs were there.  The next closest body of water is a tiny creek about 200 feet away, so I guess that they migrated from there.  But that seems like a pretty long (and dangerous) pilgrimage for a frog.

:-)

[Wasagi]

 Hahah, that sounds like quite an adventure for a frog!

Thanks!

[Kai-12]

This is an awesome instructable! I have wanted to make a backyard pond for several years now, but I'm waiting until I move to a more long-term dwelling.

Prospective pond-makers take note: you can help out your local environment even more by not putting in introduced goldfish. Fish-free ponds are much nicer for the native amphibian life, which is sadly dwindling in many areas!

I know most people prefer fish in their ponds, but consider one without fish, especially if there are endangered amphibian species near where you live. Your pond could be the only suitable breeding site for many kilometers around.

[truemirror]

so amazing, it reminds me of the time I spend at a beaver pond, it started as a tiny small creek/spring running through a mountainous forest, after the beaver stopped up the crick, than the ducks and storks brought in fish, turtle, frog eggs and pond weed in on their feathers, than all wild life start making paths to the pond where normally there wouldn't have been a body of water, than new types of plants start to grow where before it would have been too dry. I once made a small pond using a bucket, and before I knew it it became a wild life watering hole along with snakes, turtles frogs and of course I put in one small gold fish to eat the mosquito eggs. It still amazes me. after reading this article I think I will try something bigger.

[A good name]

I'm very interested in this bucket pond... I don't have the room to make a full pond to put in my backyard (well I DO, it's just much too close to everything else) and I'm considering trying something like that... Out of curiosity, what sort of bucket did you use, and how big? Did you ever need to feed your fish?

[truemirror]

The bucket pond I did, I got a deep black bucket from the automobile department at the store. I dug a hole deeper than the bucket, dropped the bucket in, filled it with water, placed heavy stones around the rim, some sticking over to hide the rim, and then one in the bucket so birds could stand on it, after letting nature take its course to condition the water, I added a few small gold fish, the ones that survives the animals and elements usually will live through the winter, or you can bring it inside, gold fish won't grow bigger than their environment. I let some leaves fall in and allowed it to go murky, soon though nature takes over and it clears up, it rains a lot so I didn't have to worry about refilling it too much, I fed the fish everyday in the beginning. or when there isn't a lot insects, and planted herbs around it. The deeper the bucket the better survivor rate for the fish from animals and winter. It's not too impressive but gave me a little corner in life to sit, watch and enjoy. not too good if you have children though, they may step in it. Or a if you have a huge dog he can drain it in one day.

[A good name]

Hmm... this is interesting. I wonder if I could go ask the elementary school I used to go to if they have any of those desk bins... If they do, I'm in luck :)

[truemirror]

Do an instructable on it, I'd love to see how your little pond turns out. :) (is a desk bin deep enough? maybe a food bucket from dunkin donuts lined with black plastic? though you would want it wider, or maybe one of those huge industrial mop buckets just a thought, check out the thrift stores) keep us informed.

[A good name]

Nah I figure a desk bin should be big enough for frogs... that's all I want it for, but since my dad's doing construction outside right now, I'm going to have to wait until it's all done.

[clockworkdoorbell]

Great Instructable. Can I ask about sun/shade balance? We've thought about putting a small pond in, but reckoned that it wouldn't get enough sunlight.

[Bitsi]

Yeah, that can be tricky. Because too much light will encourage an algae bloom that will take over your pond. And if you have shade trees, the leaves will drop into your pond and create too much decaying matter that will change the biological balance. The usual rule of thumb is that you need about 6 hours of good light daily for shade-loving plant growth like hostas. If you have more hours of daylight than that, you can consider other types of flowering plants.

[iya]

you are clever and a joy to read...do you know if fish could survive the winter in Regina, Saskatchewan, Canada that is...Thanks so much!!!

[NobodyInParticular]

What if you located the pond over your sewer line? A hot shower and some dishwashing every day, in addition to heat from decomposition, might keep the pond warm enough.

[Bitsi]

I am ashamed to admit that I had never even heard of Regina, SK until now. Looking at a map, I see that you're pretty far north. The important thing is to keep the water from freezing completely. The fish can live in very cold water, if it's liquid. You can achieve this by a) making the pond so deep that it can't freeze solid, and b) using a heater or bubbler to keep a portion of the surface ice-free.

[BonifaceJ]

Another trick that works: Build a form out of blue insulation styrofoam that matches the shape of your pond or is slightly bigger (really only works for small ponds) and make it thick enough to insulate well. If done right, this will keep it from freezing as well, especially if you have fish. In the winter most fish either don't need food or only need it once a week or so anyway, so make sure you have a way to get to your pond in the winter.

That's how a friend does it here in Alaska. :)

[iya]

do you know what kind of fish, i don't want frogs because i run a daycare, thanks!

[Bitsi]

I love the idea of little kids learning about nature from your pond. Be sure that you never let them near it unsupervised though, especially since it's going to be pretty deep to keep from freezing solid in the winter. It might be hard to keep frogs OUT of your pond. They tend to just show up wherever there's water. I don't know how they do it. It's sort of amazing. Anyway, you can buy any kind of cheap (comet) goldfish they sell. They cost $.20-$.60 a piece here in Ohio, depending on where you get them. If you manage to keep them alive for a whole year, you can invest a little more by getting shubunkins or sarasa (a fancier type of goldfish). If you keep those alive, you can try koi. Even small koi are $15 here, so don't buy 'em unless you're pretty sure that you won't kill them. :-)

[estuvam]

where do you get your Koi? i live in columbus and a friend of mine has expressed and interest in getting some.

[Bitsi]

There are lots of places around Columbus to get cheap and/or quality koi.  I recommend Aquarium Adventure, because they have a nice selection in every price range.

But if you are northeast, try the Sunbury Garden Center.  They even have tadpoles!

[JOEDUPONT]

I just bought some 12 cent comet goldfish from pet smart in Watchung, NJ and brought them up to PA. I have them in 5 gallon buckets with watercress in my greenhouse. I doubt the water will freeze inside. It would seem that the plants will love their fish buddies.

[killarowa]

whats the difference between regular frogs and "aquatic" frogs? do they not come out of the water at all or are all frogs considered "aquatic"? I must be missing something...... Did you dig out your pond by hand and shovel? How big is it? Do you use a pump or just keep close eye on vegetation/bacteria levels? Whats the max depth of your pond? Whats the dealio with the lily pads? transplanted them from another pond? And i think ive heard before, that if your water is too green/murky add some hay, im guessing so it can rot, sink to the bottom (or float around till you pick it up later) and produce oxygen.

[DIYDragon]

Those 'aquatic' frogs; if they're the pet store variety I think you mean don't come out of the water. They're pretty cool little critters though - And grow large if you have a big space. I bought some for my Dad's pond, and they are quite impressive specimens now when you see them! It's hard to catch a glimpse sometimes though, because they're very good at hiding. : )

[Bitsi]

That's a lot of questions! Aquatic frogs... I dunno. The ones in the pet store don't seem to need a place to sit and breath air. My current pond is 20'x20' by 3 feet deep. There were too many rocks for us to get very far with a shovel. So I had a fellow with a back hoe dig it. Then my husband I and I shaped it, and put in the rocks and plants. I have a pump and a waterfall that keeps the water circulating (and sounds pretty). There's a mesh mat that keeps leaves and algae out of my pump. But most of the water conditioning comes from the biological balance. Got the lilies from a watergarden store. It was late in the season, and they were on sale. What you see in the photos is the result of being in the same location for three years. You can add barley 'straw' to your water and it does help some. It's supposed to float though, not sink. Basically it introduces desirable bacteria to your pond and gives them a habitat. Only barley straw works though. Don't use hay. :-)

[goodfishfive]

When barley straw decomposes it releases small amounts of hydrogen peroxide into the water. This small amount of hydrogen peroxide helps to keep algae levels down. Don't add too much or you'll potentially kill your beneficial organisms and bacteria. (Nice looking pond by the way.)

[brabantia]

Super cool instructable. I didn't know I wanted a pond before reading your article, now I've decided I'm going to get started on one this coming weekend!

[Bitsi]

THIS weekend? Really? Do you live somewhere really warm?

[brabantia]

well not REALLY warm, but pleasant: south of France

[Bitsi]

Well, according to my map, the south of France is still a bit north in the US. Although I don't know... I've never been south of Paris. Anyway, I'd recommend starting your pond in the spring, when the earth is softer and your plants and fish have time to get established before the first frost (which we had this week). :-)

[bedeboop]

I love this! How deep would you have to dig for Zone four, or is it feasible for Zone four?

[Bitsi]

Sorry that it took me so long to respond. I had to search for this map. Click this link and look at page two of this document to find a frost depth map of the US. http://www.usace.army.mil/publications/eng-manuals/em1110-1-1905/c-2.pdf#search='frost%20depth'

You need to make part of your pond at least this deep so that the fish don't freeze solid in the winter.

:-)

[ronniedd]

HELP!! I got the kids a paddling pool to discover it was full of tadpoles one day plus 2 other form of life. Reckon there are about 500 plus, have just let them be for the last couple of weeks. What should i do??

[Bitsi]

Ronnie -- If you are absolutely sure that the creatures are tadpoles and not some sort of parasitic worm, they should die off on their own pretty soon. I mean, I doubt that you have all of the necessary ingredients for animal life in a paddling pool. How long have you let that thing sit anyway? :-)
