I have Koi..never have followed that rule... BUT Useing the rule
described below you are saying that you need 1000 gallons of water to
succesfully keep one KOI Healthy??? I disagree.... MIKE

What I am saying is that you can keep a Koi alive in your kitchen sink with
the proper filtration. BUT, since none of have our ponds in a labratory with
carefuly monitoring filtering, it is good to give some buffer space to
prevent large swings in the water parameters. The 1000+100 rule is a good
rule of thumb for hosting a pond full of Koi, simply because it provides an
easy to remember number, and enough water to properly buffer spikes in water
chemistry. In addition, as Sam pointed out, 1000 gallons will often result
in a size and shape pond that gives the Koi room to move.
