OK folks,
One more thing I want to mention that Dunkel has a very special design for the pond and filter house system. There is no other koi filter house system like Dunkel. There is something that I think koi kichies would love to view... So here is your chance to attend the ZNA NorCal meeting and get Dunkel pond tour for free;-))
Here was the thread on koi-bito about Dunkel's unique koi pond and filter house system....
The Dunkel Pond
