I had a 6000 gal koi pond. Filtered by 2 double showers with 100 kg of bacteria house media in each shower. The watwr was fed to the showers straight from the 2 bottom drains no pre filters the flow rate was around 11000 gals per hour over the showers. Ran it like this for around 3 years before moved house. The nitrates in the pond ran at near zero. The water was clear enough to see to the bottom of the pond 6ft deep.
Never had to clean the media once in the 3 years.
