One unit? sheesh, I bought 3 for my 1000 gallon pond... like they say there is never enough filtration...
Maybe I should get a bigger pump...
Poor guppies maybe I should add more than two in the pond?
(Just Joking)
Wow! that thing IS impressive though and probably a lot quieter than the 3 to 5 tray setup.
Now if I just had that much (10K) to build my pond....
