Being a keen keeper of most things animal related (have lizards, tropical & normal aquariums, dogs and a budgie), I thought it was about time I took back part of the back garden from the other half for a small pond. So I thought what better thing to be doing in the scorching heatwave that we had this weekend (25th June - 27th June 2010) than digging in a pond! Not the cleverest decision I've ever made I know lol.

Now before I made the transition to a half-decent sized pond, we did have a very small pre-formed pond liner surround by decking...you know the sort you see in garden centres etc. It was about 1' deep and around 3' in diameter, and had a few small shubunkin's and goldfish in. Fortunately, I did have the foresight that I might one day get off my arse and build myself a proper pond so at the same time I also bought the following: Hozelock Ecoclear 5500 kit. This comprised of the following items: Bioforce 5500 Filter & Titan 3000 Pump both of which combined should be capable of supporting a high density stocked pond up to around 5,500ltrs. Totally overkill for the tiny pond that I bought at the same time, but when the other half gives you permission to spend some money, your wise not to miss the opportunity!

Moving on to this weekend.........

After giving some thought to what shape and size of pond I wanted, I had to have a rethink as it turned out my idea was to big and the other half wanted to keep at least some of the grass. After all the dogs do need somewhere to do the business so that only seemed fair. The pond will be situated in a corner of the garden that currently gets shade cover all the way through till approx 13:30 during the summer days.

After the rethink and agreeing a permitted area with the other half, the following pond size was agreed on: 6' long x 4.5' wide x 3' deep. At one end of the pond there is a shallow shelf that's about 9" deep by 12" wide that will be used to put some planted pond baskets on. At the other end was supposed to be another deeper water shelf at about 1'6" deep down and 12" wide, but I got a bit over enthusiastic with the pickaxe and spade and the shelf ended up being around 2'6" deep down instead..... :whistle: So I reckon, and by my calculations, I have a total pond volume of around 1,912ltrs/ 420gallons or so. I do have pic's of the build as it went through its various stages during the weekend, and will post them up when I get chance this week (hopefully sooner rather than later).

When I took the filter and pump out of the old pond, I made sure to leave as much old pond water in the filter as possible as I assumed that this might aid the start up, biologically speaking, of the new pond. But thinking about it now, how long would the "good stuff" stay good for in the unused filter? If its still good, would it mean that I would have less chance of suffering from new pond syndrome, and be able to stock the pond with the old fish quicker than if it was a complete new pond and filter etc?

The old fish are currently in plastic containers at the moment with an air stone in each and netting over the top to stop the local cats getting at them, and at the moment they seem fine and healthy. But I obviously don't want to keep them in these any longer than absolutely necessary.

The pond is now full with water and has been treated with Tetra Pond AquaSafe. The pond still needs edging and finishing off properly yet, but after a weekend of digging and moving an unknown quantity of wheelbarrow's worth of soil/clay I was to knackered and decided to call it a day. Also along the way I had a slight disagreement with the pickaxe, and it jumped up and hit me in the head and while filling the pond I decided to demonstrate to my daughter how dangerous ponds can be by simulating a slip into it (in reality I slipped on the lowest self and fell backwards hitting my back/ribs on the side of the pond before ending up sat in about 2' of water :oops: ).

At some point in the not so distant future, I plan on adding an Oase SwimSkim 25, to help try and keep the surface clear of debris etc, and this will be put on a timer to come on two/three times a day for 45mins/hour at a time.

Forgot to mention that I couldn't have got in all done without the help of my father-in-law :)
Thanks for reading, hope I didn't bore you all to much, and look forward to hearing all your comments and feedback etc.

One thing I'd like to note to you is that your filteration system is theoretically suitable for a pond of up to 5500 litres however what they don't normally clearly state is that, that pond would be totally covered in shade and also not contain any fish stock. Practically i.e. with a pond with a reasonable amount of fish in and in full sun I would guesstimate that it would only be suitable for something in the region of 1250 litres.

As such long term I would potentially recommend a new filter minimum and potentially dependant on the "head" you are pumping too a new pump as well. Otherwise pagoda's look good this time of year...

Oase do a nice set of pumps and pressurized filters (If a tad expensive) :)

Here are the stats of both the filter and pump, as people may be able to shed more light on there actually abilities etc:

Also remember, as per my first post, the pond doesnt get any direct sunlight until approximately 13:30 most days anyway. The pond also has an additional airstone in it now, and it also wont be heavily stocked :)

It was hot, sweaty work thats for sure!

You didn't do any of the digging! :p

I know nothing about ponds, but in relation to its depth i'd go longer for the deepest bit to take up that ledge (with the ledge added onto the end) to keep things in proportion.

Looks a bit deep for it's width/length... judging on the 2 ponds i've seen in my life :o:p

Plus when the other half isn't looking, slice a bit off the sides if you want a bigger pond... it won't be noticed!
 
Are those pine trees not going to poison the water? Nasty sap comes from them.
 
I was going to ask why you didn't go closer to the fence, then looking at the photos realised there were tree trunks there... :o

Looking good although it does look funny depth/width ratio but then deeper is fine as it means a more stable body of water. What I would suggest though is to have one side sloping up so it's easy for creatures to get out of the pond if they get into it, maybe even a stream going into it for the birds/small creatures to play in and drink from.

We have a preformed pond (fibreglass) which is around 6x3x3 ish (half of the ying/yang symbol stylee) and then a 3x3x1 nature pond right next to it, trickling in under a bridge which has sloping sides, a 6 foot long stream leading into it from another 3x3x2 pond. The wildlife love it and it gives you somewhere to put the tadpoles so the fish don't eat them... :p I'd suggest it would reduce the strain on your filter too if you got a shallow pond type area as the water will trickle through a load of plants before getting to the main fish pond?
 
The trouble I had was the amount of space I was allowed to take up in the garden. The plan is to eventually remove the shed, and hopefully then I'll be able to extend the pond down the garden that way.

Before I properly edge the pond I may try and slop the shallow shelve to allow frogs etc to get in and out safely, as per the suggestions.

The key to this weekend project was to get a pond into the garden on a budget, with the plan to extend it at a later date as and when we change the garden around a bit.

Sure the pond had a unusual width to depth ratio, but I wanted the maximum water volume possible in the space I had available. The bigger the water volume, the more stable the water will be and will also become self sustaining as well.
 
Are those pine trees not going to poison the water? Nasty sap comes from them.

A pond skimmer will get rid of any pine needles, or any organic material for that matter, that falls into the pond. I don't think the pine tress will cause massive issues with the water quality to be honest though.
 
Ask anyone with a pond, whether they built it or inherited it and one of the first things they will say is "I wish I had built it bigger".

Remember, if you are going to put some Koi in there that they produce a significant amount more waste compared to Goldfish etc so go a lot less than the number/length of fish recommended for your filter.

If you are going down the wildlife pond route then I think its about the right size, the major problem with such small ponds is due to the small volume of water, spikes in Nitrates, Amonia etc tend to have more affect, as do temperature changes. Larger volumes of water obviously are able to 'buffer' for seasonal spikes & temp variations.

If it were me building the pond I would build it hard upto the edge of the shed and bricked area near the grass, build it up a couple of feet and use the rear of the pond (under the trees) to house the filtration system, as you have dug the hole already its the perfect chance to install a bottom drain. deck the rear of the pond to cover the filter(s) and clad or finish the front of the pond in good bricks, get some fancy slabs for the top of the pond. Do away with the shelf completely, you can make some floating or hanging shelves for plants if want.

Also if you ever do decide to build a stream/moving/shallow water maybe stick in some kind of sump as well. We don't have one and over around 3 days in this sort of weather we end up with the bottom pond losing about 6" of water due to evaporation!
