6000gallons, a bead pressure filter, a shower filter, two skimmers with 10" thick worth of matala filter mat in each.. A 4" bottom drain feeding the bead filter,, a retro bottom drain feeding the shower. The two skimmers feed a 750gallon heavily planted bog filter. I have four pumps, two submersible and two direct drives, totalling 25,500 gallons of water turnover an hour through filtration (minus head pressure, of course)
I go to koi shows and have three trophies to my name .. One for best metallic koi,, one for best fish entered by a first time competitor and one for best fantail goldfish... They were hand made plates engraved on the back.
I made the fancy japanese looking wall thing to hide my filters and 300 gallon quarantine tank
