koi pond info please
Discussion
I have just bought my 1st house and it has an 1800 gallon pond in the back garden. The previous owner built it and has taken all his pumps and filters with him. Now i want to get it going again but i dont have a clue on what filters or pumps i need. So can any one tell me what sort of pumps and filters i need for a 1800 liters
Hi
Are you talking gallons or litres? You mention both. 1800 Gallons is 8200 litres so as you can see it is 5 times as much.
A lot of the pond suppliers will sell kits such as
http://www.keengardener.co.uk/product/view/5883/ho...
This one will run up to 5000 litres and has pump, uv, filter and hose. You will need mains voltage nearby (assume it is there unless they took that as well).
This one can do 12000 litres

You need to take into account the Head for the pump as well which is the vertical height difference from the pond surface to the outlet of the filter. If you have a waterfall it can be quiet high depending on set-up. The greater the head the more oomph the pump needs to maintain flow rate.
I assume he took his fish as well?
What I have shown as examples are in pond pumps. Does the pond have a bottom drain if so you need a pump to get the water back from the filters to the pond which sits in clean filtered water so needs very little maintenance. Do you have a local pond supplier most of them will come round to take a look and advise on the correct approach and they can test the water for you as well.

yes in gallons, i really havent got a clue when it comes to this so all advice is welcomed. He has taken all his fish with him i belive it was around 40 koi an a few orf. I will look at your links when i get on my home computer as work internet blocks all links. I have a local carp farm so i will go around to see them at weekend. The previous owner drained the pond but not fully so i dont know what sort of system it has on the bottom. I think i best take a proper look befor i buy any equipment. thanks
We'll need photos!
Here's some inspiration (any excuse to bring the thread up!). It's my dads and holds about 30,000 gallons.
Costs a fortune in water and electricity though.

He has 3x giant (taller and much wider than me!) centrifugal filters. They're quite clever. Water flows from the pond into the top of the filters (which look like huge barrels). Inside the barrels is a conical shape and the water swirls around. The idea is that the dirt is sucked into the middle of the cyclone and then sticks to the bottom and sides of the cone. Clean water is then skimmed from the top, down some pipes, into some (currently unused) UV filters and then into a huge pump (one for each filter). The pump then pumps the clean water up the large oriental style bamboo building. Inside here are loads of plasic crate trays (the sort of thing you see fishmongers keep their fish in), each tray holds a different kind of filtering material and they're stacked up on top of each other. In the trays are shells, various organisms and little shellfish which filter the water still. The water just simply runs down through these crates and then runs back into the pond under the decking.
There aren't any filters which need replacing at any point. To clean the large barrels you simply lift up the hatch in the decking, shut off the water flow into them and blast them clean with a hose and give it a quick scrub with a stout brush. Then rinse it again with a hose and turn the water back on. Takes 15 mins and he does it once a fortnight. The tower of filters looks after itself.

PS. I would seek some professional advice if you want to do it right and efficiently. Ponds can be expensive so you want to make sure you use the right kind of filters and make the right kind of environment for the fish you want. Do it right the first time around otherwise it will cost you in the long run.
My dad was lucky, the chap who owned the house previously bred koi so he knew what he was doing when he built the pond!
