    I am using the info I have learned watching your vids to enlarge my pretty good sized pond I built 4 years ago before I really knew much. My friends grandpa has several hundred acres of wooded land used mainly for hunting, and I am asking if I can go rock gathering. WIntering my fish indoors this year so I can work through winter and early spring to enlarge the pond. Our winters have been mostly mild lately so I think we can safely work and then come spring my fish will have a nice big home!

  20. bolloMB says:

    is it just expandable foam your using? if so couldnt that pollute toxins into the water. just curious

    Keep in mind koi get 24 to 30 inches in length. A conservative rule of thumb when raising koi is one fish per 250 gallons of water. Serious koi keepers will house one koi per 500 or even 1000 gallons of water! 450 gallons is a bit small for koi considering how big they grow. You could certainly raise baby koi for a year or so before needing a larger set up. Koi actually grow very quickly and can out grow your 450 gallons in only 12 months. Happy Pondering.
