I'm planning to take out the old, excuse of a pond:
And dig it deeper, and longer.
I'm going to start by taking the old pond out, then I will dig straight down to about 3ft and construct a wooden frame around the pond. Then I will attach mesh to the frame to stop the sides from collapsing.
Then I will add the liner underlay, and hopefully will add an L shaped box liner so there shouldn't be any folds/creases at all.
Then i'll swap 1 of the pumps, which has a poor flow rate with another one I have which has a flow rate of about 2000ltr/h. So I will have 2 pumps in, 1 powering the filter, and one powering the waterfall both about 2000ltr/h each.
And that should be it complete.
I'm going to be using Butyl liner, so I was considering putting the oulet from the filter directly into the pond through the liner, do you reckon that would be a good idea or not? I'm not sure because it wont be breaking the surface and it may make it suceptable to freezing over. Thoughts?
Also, I want to keep Koi in the pond, what depth/size or volume would you recommend to be able to keep big Koi healthy?
And of course I will be photographing everything I do, so when i'm finished i'll post the photos with a write up on here.
oh i see, i was judging from the first picture! I didn't realise you were making room at the other end! I was suggesting that you could lose the wooden feature and fill that space as extra room for pond. L-shape is more interesting than a boring rectangle anyway!
sorry... cant help on that front. I know nothing about koi carps except they are massive when fully grown!! just thought it may dislodge itself on the small part of the pond but I am rubbish working out the scale...
I guess the decision on depth will be down to the cost of the liner, and i've heard that about the cold winters too, currently the pond is only 1ft (i did it before i knew anything about fishkeeping) and i was dreading the winter.. luckily they have survived, but there was fry in there too so i wonder if any have made it..
So, seems im going to be using Butyl liner, do you reckon I should run the filter inlet/outlet pipes through the liner and underground? It would make it look better, but i'm worried that it might make the pond more suceptable to freezing over because it wont be breaking the surface of the water..
