Yea I know I’m biased, but just get an AEM drum followed by a JBR bio filter for under £1500. My pond is 5500 gallons and that set up is working perfectly for me (and my koi).
Admittedly I already had the 200 litres of K1 but I cannot stress enough how getting the drum and bio filter has transformed the hobby for me.
I have been keeping koi for many years and initially couldn’t justify the high price tags of the original drums, but when AEM brought one out for under £1000 which also includes an integral UV I took the plunge.
So glad I did because as I get older I can do without constantly climbing in and out of the filter bay to clean the filters etc.
I virtually have nothing to do maintenance wise so I have more time to enjoy my koi and take more interest in their health and well-being.

The second one you link to is just the drum module, includes no bio so you are only getting the drum and need to buy a second filter anyway.
Unfortunately 'small footprint' and 'koi pond filter' are not 2 things that generally go together. Bio needs surface area, and that requires space. Bead filters and showers are the smallest footprint bio filters.2016 new 6000 gallon pond

Just a caution - never take the max flows declared by manufacturers for granted - their max flow rates should be divided by 1/2 to understad true potential - declared max flow is really this - max flow - not normal efficient flow rate - just food for thoughy....

Just illustration of what Feline pointed out correctly - my filter house - in pumped setup - is 2.3m by 1.4m - housing 600l IBC tank in which I have built Anoxic filter - but equally well it can hold moving bed with K1 or Hel-X media (up to 300L of it), on top of it I have AEM Easy Drum on the right end - and on the left end two denitrifying trickle towers - with 100L combined Hel-X 17mm media, on the outflow from AF I have small Bakki Shower with 40L of Ogata Crystal Bio - on the other side of filter shed there is Bakki shower combo with combined 130 L of Ogata Crystal Bio and 50L K1 - not really much more space for any other filtration there - outdoors - on heating line I have the latest addition - shower filter with 100L of Hel-X 13mm media - all of the filters DIY - only drum purchased.

If interested you can check either Bakki shower DIY link here - https://www.koiforum.uk/water-treatm...wer-combo.html
or the outdoor version here https://www.koiforum.uk/water-treatm...or-shower.html
Both use square 300L rainwater harvesting tank as their filter housing - it can be equally well used also for moving bed if it is personal priority (one can hold up to 150L of K1 or Hel-X media) - I opted for shower filter design as in my pumped setup - if any power outage or pump failure happens, the water empties the shower filters - and no risk of going septic with nasty bugs outgrowing the good ones - but scientific reports indicate, that moving bed design might be more efficient for nitrification than shower design - against popular beliefs - but it all boils down to personal decision and preferences - everyone is free to choose from.
Good luck!You get what you pay for - or better - what you make yourself.
