Hi Freeliner,
I have the same on my 12500ltr pond - as a newbie to koi keeping like yourself you learn by your mistakes, don't get me wrong they do the job but there are a lot of maintenance involved in these filter systems.
Things to watch:-

UV bulbs sit in a testube glass chamber which can leak and fill with water when backflushing causing bulb to fail

Hose connection leaks under pressure so use some plumbers tape to seal and tighten with waterpump pliers

constant clogging - instructions say once a month strip down and clean, but I've found it needs doing every 2 weeks.

I would say these filter would be very good for goldfish ponds but Koi they are just not up to the task.

Goodluck

i had the twin model running from my skimmer , up until 3 months ago ,

i'l eco darrens comments !!

there's nothing wrong with using the returns from the twin setup , to feed a good bio filter

i also have the twin hoselock bioforce 18,000 filters with the 11 watt uv in each as thease are both 9000,s but as a combined unit there 18000, which would you say would be the ones to use

must say , i had a bio force twin 18000 for 11 years !!! always kept the water crystal clear , but like most pressure filter types , there very poor on bio filtration .
