There are about 5 smaller ponds that cascade into the largest one which has koi in it.

Now the top one leaks. I have bypassed the waterfall into the second pond using pool hoses so everything works normally.

How do I seal the top pond? It has had membrane and bitumen type stuff on it.
I will have to remove what remains of the membrane and repair the cracks in the...

So we moved 11 fish to the duck pond - no ducks any more as we got a husky.. I also moved some floating plants across.

Not sure of the exact amount of water the final pond will hold, but it will be in the region of 1500-2000L.

Outer dimensions of the pond are roughly 3m x 1.2m. It will be built out of double layer brick walls, with concrete foundation, and will again be a raised pond (the foundation will be below ground level but the walls will be above, somewhere between 70cm-1m high, I'm still figuring that out.

We've got a guy building it...

The part marked in yellow is about 1,8m wide (from the wall to the edging) and the main section about 2m long (excluding that possible little extension). So unfortunately still pretty compact.

Plan on starting tomorrow by removing the plants and our gardener can start digging. The area in blue is where I think the pond should go (my current 150L molded plastic one), sunken. The idea is to dig everything out about 75cm deep,...

(ignore the painting behind the bag, it's a project dh is working on for his studies)

Got the wood for the basic frame of the pond, 24 x 1m lengths. So it turns out it's going to be a 1x1 instead of 1x1.2m because they didn't have enough 2.4m lengths of wood at the store. It should still work out to about 700L though because I think it will be slightly higher than I originally thought, due to the width of the wood, so I should be able...

I currently have this empty pond which is situated on my front porch . its been standing empty since December due to evaporation . The water was very brown and dirty as there is no filtration . the main problem is that any filtration will just get stolen as the area is easily accessible. The previous owner also mentioned that his goldfish was stolen from the pond . I allowed the pond to dry out over the summer months as you can see in the 1st picture . My plans are to refill the...

I'm aiming (at this point) for a 1.2m (L) x 1m (W) by 75-80cm (H) pond. The water will only be filled up to 60cm though (reason for extra height is that I have cats and don't want to make for easy fishing). It will be an above ground (raised) wooden pond, based on this type of design:...

Incredible effort has been taken in the design and planting. As far as I understand exclusively indigenous plants with a focus on biodiversity.

The site is sheltered from the winter elements and there is access to electricity so I can run a filter. Gets sun from about noon/11am.

I have some leeches in my pond from salvinia I collected from a dam.

Any advice on how to get rid of them would be much appreciated.

after selling most of my pond guppies, I was left with a lot of juveniles.

put them in a large tub, filled with pond water and a lot of water cabbage and a 150w heater.

Water is circulated, no filtration. All seems happy
