LOL lildude...But, at least you had some sort of filtration....I can not begin to tell you how many of my customers have no clue as to what filtration is(they seem to think it is the little foam sponge attached to the pump) so you were still up on most of my customers
of course after they leave here they are aware of what both mechanical and bio filtration are.....as for my first pond it was 3x3x6 hole in my yard that I lined with a pool liner and had no filtration, no pump and housed only squeeter fish, cattails and a lily...I didn't even know what a koi was untill about 7 years ago....
