Buy a shedload of fine filter wool and place it in the last stage of the filter chamber. change/clean it it every time the filter pump rate slows and repeat until the water is crystal clear.

Filter floss blocks very easily, where do you think the water will go when the outlet slows down?? Outside the filter box then onto the floor.

To me they look likeKohaku ,noticed the prominent dorsal,the colours are nice and defined,my father was a founder member of the BKKS..
Spent a LOT of money my dad did,I'm not saying there is,or isn't but a few of his poor definition kois could be still in a 117 acre ressi,...who knows.. Lol..

Winter & cold water will be why most are laying on bottom in an almost dormant state.

Net the one that is not acting right out & do a skin scrape & check gills at same time for flukes or anything else.

I have koi in tanks in the house that are going barmy at the moment even though it is cold, as well as a raised pond of Leney descendents which are still feeding like crazy, yet in the raised pond adjoined to the one with the Leney's in (same depth just a little longer & separated by an 6" sleeper wall) which has 25 x 8-12" Karashigoi & Chagoi Tosai in it, the fish are not moving at all (Jap blood line but spawned in England), in the same way all of the fish in my 14500 litre pond are all laying dormant (few suffering from Carp Pox but can't do much about that TBH)

I can recommend joining “extreme koi”, it's a pretty decent and well run forum.
Also, if you haven't seen then already, Kev”s “Koi Nerding” videos are a good watch. I know he's at the high end of the koi hobby so most of us mere mortals who run drums have a similar setup just scaled down.
I think jnhes got at least 2 drums and a few flowfriemd pumps. His setup is amazing and the fish are something else too.

At the moment, all my Golden Orfe are usually just under the surface swimming about even when there is a bit of ice on the water. The carp and goldfish are all down on the bottom tucked away next to or in the rushes and the rudd sat midwater.

As for water temperatures, I think it is consistent almost throughout the pond as I have a large pump and filter system and the whole ponds water in theory is recycled 4 times an hour so is consistently moving. If the Golden Orfe are not on the surface then they are holding position close to the bottom swimming against the flow of the water from the inlet. On occasions they are joined by the carp.I can tell where the fish have spent the night and if they have been feeding by the droppings left on the bottom. Oxygen should not be an issue as I also have an aerator as well working.

The largest carp on occasions likes to try and swim up the flow of water from the inlet, I do not know why but I just think its there exploratory instincts trying to find out where the water is coming from. I actually had to remove the inlet pipe further into the pond and away from the edge as the large carp would keep trying to swim up the flow of water and could get very determined at times and get a good lick of speed up and would not be far from flying out of the pond.

The fish love playing in the flow. In both tanks of this years fry that are growing on, when a water change is carried out, the fish literally queue up in the flow from the water inlet & are porpoising over each other like salmon trying to climb a weir pool! These are fish that are less than 8 months old! Even the last batch of fry in another tank (6 months) sit in the return pipe flow from the filtration even though it s no more oxygenated than the actual water in the tank as the pipe is below the waterline. Oxygenation in the pond this time of year shouldn't be an issue unless it is frozen over as colder water holds a lot more dissolved oxygen than warm water.

Water turnover of 4 times an hour is extremely high! Once every 2-4 hours is the recommended level for optimal filtration (especially if you are using UV clarifiers as if the water goes past them too quickly, then it is not affected by the UV light. The longer the water is in contact with the biological medium in the filters the better the filtration will actually be as the bacteria has more time to perform the nitrogen cycle.

Turnover rates really depend on what type of filter you're using. These days with modern ceramic media in a "shower" situation, it's not unusual to turn a pond over every 30 minutes. My shower can run at 30k l/h, it's set at around 20k l/h whereas my K1 chamber is running around 15k l/h. All my inlet pipework it 4" and return pipework is 2".
Pipework size/bends/restrictions also play a part on how fast you can pump the water around your system.
An old multibay type system wouldn't be able to handle a huge flowrate, neither would a Nexus, they just weren't designed to do that.
Modern pumps are for more powerful and efficient than they were 10/20 years ago. Back then we used to use central heating circulation pumps. These days, you can pick up a variable speed Jabeo for around £120 that can comfortable pump 20k l/h, possibly more.
A budget drum filter is around £950 and a lot of people are changing now from sieves/beads to drum/shower as it pretty much automates a lot of the cleaning process along with taking all the crap out down to 70 microns (ish). The waste gets flushed down the drain or over the garden which means i'sl out of the system straight away rather than sitting in brushes/filter wool/sponges etc until it's manually cleaned out.

No pond is the same, you have to find the right system for your needs and budget.

If I had a tenner for every time someone told me "I've got this pressure/black box filter and my water is rubbish on my koi pond" I'd be a wealthy man

Oxygen wont be an issue this time of year due to the temp, as suggested the fish acting strange does sound like a health problem probably parasitic. Most parasite activity will slow down but not as much as koi pro rata if you get what i mean. Thats why health problems can be worse spring time as the fish arent up to full strength. The issue you can have is treatment a lot wont work in colder weather, in fact an fmg based treament the formalin can turn toxic. A potassium treatment might be a good shout but i would ring a company called NT labs they specialize in treatment and are normally helpful. Again as suggested the only way to tell if there is a parasite problem are microscopic scrapes of the fish slime. If you have a local koi supplier they might help with this, dont take the fish to them in a bucket though as i used to see all the time!!! Check for any blood vessels on the surface of the fish this is a claasic sign of parasites/stress.

Might be worth forming it from concrete rather than blocks mate, be way stronger obviously. As for lining, carpet underlay is a good shout, with some sand underneath it
Are you sure?

This action cannot be undone.

Yes, continue
